Executive Summary
The 38 partners of EuCARD (European Coordination for Accelerator Research and
Development) are engaged in development of state-of-the-art technologies to upgrade major
particle accelerators in Europe. During the final 12 months, the project has achieved most of its
objectives and technical goals, and published some 150 scientific contributions.
WP2-DCO maintained the project web site with latest project related news, has collected over
500 publications in the publication database. As a result of an initiative over P2, we extended the
scope of the quarterly project newsletter and created a combined newsletter of 4 other projects,
enhancing their synergies. 6 issues have been published during the period and 7 additional
accelerator science monographs. WP3 (neutrino accelerator facilities) has produced reference
documents on scientific policies with respect to research infrastructures that were timely
submitted to the European HEP Strategy sessions. WP4 accelerator networks organized or co-
organized 25 well-attended workshops in various fields of accelerator sciences with concrete
outcome. Two major synthesis documents were produced, defining possible strategies for the
future of frontier accelerators and pointing to the required R&D.
The HiRadMat irradiation facility at CERN (WP5) successfully operated during the beam run
in 2012 and hosted all 7 scheduled TA experiments for data taking. 102.6 access units have been
delivered in P3. Under WP6, the TA activities continued successfully with 1107.7 access units
delivered. Principal goals of the user groups were the development of high precision diagnostics,
which proved successful.
The Joint Research Activities are the project’s backbone and enable or reinforce tight links
between European laboratories, institutes and universities, as well as two SMEs. Achievement
highlights include:
- WP7 (High Field Magnets): to mitigate the high risk of this novel Nb3Sn high field magnet
model development, additional steps have been introduced, leading to a revised calendar. The
progress accomplished gives much hope of final success: The mechanical structure of the magnet
has been completed and tested at LN2 temperature, the coil tooling has been delivered and a test
coil with Cu conductor manufactured. Nb3Sn strand for one magnet is delivered, the cable
designed, showing less than 5% degradation, well within the specification.
The HTS insert magnet components are procured and the YBCO conductor delivery expected
by September. A test coil was constructed and will be tested in September. The insert will be
finished end 2013.
The HTS link was cabled with two cabling machines and is now finished.
Two helical undulators were built and one was tested at LASA where problems indicated the
need for important design modifications.
For the support task the design and construction of all the cryostats and tooling for the irradiations
and sample tests have been completed. The irradiation of all the electrical samples and half of
the mechanical samples has been completed and some conclusions on the suitability of insulation
materials have been formulated. The thermal studies have been completed and HeII cooling
models were produced.
- WP8 (Collimation and Materials) has complemented the theoretical studies on new materials
by irradiation tests at the HiRadMat@CERN facility, with very promising results on Metal-
Diamond and Metal-Graphite composites. An important outcome of this activity has been the
creation of a multi-disciplinary collaboration, the activity of which will continue. In addition to
collimators and cryo-catchers already completed in P2 the optional test of crystal collimation
was carried out, with a measured significant increase of the particle channelling.

- WP9 (Normal Conducting Linacs) The integration challenge of the CLIC module was
exercised and its thermo-mechanical stability studied by numerical analysis and soon
experimentally after the upgrade of a dedicated test laboratory. The mechanical stabilization to
0.5 nm at 1Hz was demonstrated in an accelerator environment, validating the strategies and
equipment. The even tighter requirements for the final focus are now close to being fulfilled.
Tests in ATF2 (Japan) have allowed developing strategies and instruments for accurate beam
control; the experience gained should direct further developments to reach the accuracy required
by linear colliders. Both the electromagnetic and electro-optical phase monitors reached the goal
of an accuracy of 20 fs, suitable for the synchronization of the drive and main beams in the two-
beam accelerator concept.
- WP10 (Superconducting Radiofrequency technologies): The vertical electro-polishing setup is
completed and in use. The proton linac cavities are in the manufacturing and test process shared
between the manufacturers and the research laboratories. Delays at the manufacturers will delay
the final tests by a few months. The progress in the LHC crab cavities has exceeded the goals of
EuCARD, with the fabrication of a Nb crab cavity. The CLIC crab cavity was fabricated and the
LLRF for both developed. Good progress is achieved on magnetron sputtering, with high RRR
values, uniform films and much reduced deposition time. An EuCARD monograph was
produced on sc RF technologies, including aspects of thin films. The HOMBPM’s on the 3.8
GHz cavities was validated. Modelling and experimental studies show however that the inverse
field problem to identify cavity features from HOM signals is very difficult; nevertheless, results
obtained justify further investigations. The µTCA LLRF was finalized, installed and tested at
FLASH, already yielding a significant improvement of the field stability. Two set-ups for GaAs
cathode preparation showed contamination, and low quantum efficiency after activation. Lessons
learned allow an on-going development of a more advanced state-of-the-art preparation system.
A remarkable progress was the first FEL operation with the SRF gun at ELBE in April 2013.
The design of the automatic coupler cleaning has evolved, and the studies allow a complete
overview, including feasibility and cost.
- In WP11 (Assessment of Novel Accelerator Technologies) the final study of the crab waist
scheme applied to the LHC upgrade was completed, while additional work of the partners have
further consolidated the deliverables already provided during Period 2.
EuCARD management contributed to tightening links between leading actors in accelerator
R&D and creating sustainable European collaborations. A highlight of this activity was the
organization of the workshop “Visions for the future of accelerators”, combined with the
concluding EuCARD annual meeting and EuCARD2 kick-off meeting, attended by more than
180 experts from all around the world.

1. PUBLISHABLE SUMMARY
European Coordination for Accelerator Research and Development
The EuCARD project gathers 38 European partners engaged in state-of the-art technologies to
upgrade major research accelerators. The main components and objectives of the project are:
Networks, focused on communication and dissemination, neutrino physics facilities,
performance of hadron colliders and accelerators, and RF technologies, resulting in 40
leading laboratories worldwide being associated with EuCARD.
Transnational access facilities, offering precision beams and muon cooling setup, and pulsed
irradiation for material testing.
Joint research: 21 R&D tasks grouped under the following themes:
o Investigating the feasibility of new superconducting magnets and electrical links
using Nb3Sn and/or High Temperature Superconductors.
o Investigating the gradient limits for radiofrequency (RF) accelerating structures,
whether normal or superconducting, together with specific issues of linear colliders
such as extreme geometrical stabilization.
o Developing more robust collimators for the protection of accelerators in operational
and exceptional conditions.
o Supporting investigations on novel accelerator concepts, such as crab waist crossing,
fixed field alternating gradient and plasma wave accelerators.
The EuCARD project has fulfilled the vast majority of its
contractual goals, and in some instances of added goals
liable to reinforce the community. The TA’s have
delivered their access units, the NA’s have strongly
stimulated the community and the JRA’s fulfilled its
deliverables with few exceptions: all 63 deliverables are
delivered. One high risk deliverable gave account on the
progress made and of the planned calendar for completion
(1.5 year delay).
The number of
peered-reviewed
journal
publications
peaks during this
P3 period to reach close to one per task.
The communication network (WP2-DCO) has
regularly maintained the project website, provided
support for the Work Packages for using the Intranet and
the CDS publication database. The public website was
further developed to ensure that the JRA’s websites are
linked to the administrative and technical databases and

kept archived for the future, especially for the follow-up project, EuCARD-2. The number of
publications has reached the impressive number of 500 and over. The number of PhDs resulting
from the project has also reached 46 during the lifetime of the project and a few are still in
progress. The role of Ph.D. students’ involvement in EuCARD realization is very important and
the contributions are clearly visible in the project final achievements.
The outreach section of the website was also maintained. The quarterly project newsletter has
been replaced with the Accelerating News which extended the scope of the distribution with
more than 1000 subscribers (status on 24 July: 1046). During the period 7 additional volumes
were published under the peer-reviewed Editorial series of accelerator science monographs,
therefore reaching 18 volumes. EuCARD results and developments were reported internationally
at numerable professional conferences in Europe and outside.
The WP3-NEu2012 has finalized three strategy documents defining roadmaps for existing and
future neutrino facilities. An important event, the second EU Neutrino Strategy Workshop was
organized in May 2012, attended by more than 135 neutrino physicists, where the roadmaps were
discussed and endorsed, and submitted to the European Strategy for PP Symposium in Krakow
in July 2012. During this period, existing results came from existing facilities, reassuring the
importance of this branch of HEP, but challenges emerged for the future, with the conclusions
of the EUROnu costing report. Bringing the European and world community together becomes
even more important to face such challenges.
Over the reporting period, 25 workshops, mini-workshops and working meetings were
organized or co-organized by the accelerator networks (WP4-AccNet). Topics addressed
included quench behaviour of superconducting magnets, optics corrections, crab cavities, and
electron-cloud measurements, modeling and mitigation; design parameters for future circular
e+e- or hadron collider Higgs factories and a long-term strategy for high-energy frontier
accelerators; laser-system and FEL options for a future Higgs factory based on a recirculating
linac “SAPPHiRE”; solid-state amplifiers, low-level RF for SC linacs, and RF costing
techniques; and coordinating the plasma-
accelerators community with the purpose of
transiting from demonstrations of principle
to concrete accelerator projects. These
events have attracted world experts and
generated concrete results. A significant
number of expert exchanges have been
supported, including from non-EU
countries. Collaborations of European
accelerator institutes with the European
Space Agency and its partners, with several
Mexican institutes, and with a number of key
universities in Japan (Hiroshima, Kyoto, Tohoku) have been stimulated.
The open access facility HiRadMat@SPS (WP5-TA) successfully operated during the CERN
beam run in 2012, with 7 experiments having completed the data taking. These first experiments
included candidate materials and prototype assemblies of LHC collimators foreseen to operate
at the ultimate LHC beam powers, experiments on vacuum windows, detector calibrations and
target material options for high power proton beam applications. 102.6 access units have been
delivered in P3.
Under WP6, the TA activities continued successfully with 1107.7 access units delivered.
Principal goals of the user groups were the development of high precision diagnostics. The

performance and operation of Time-Of-Flight counters has been one of the principal goals of the
TA-supported groups from Bulgaria, Italy and Switzerland. The TOF counters have been
essential both for identification of the beam particle and for momentum measurement. Thanks
to their outstanding performance, it has proved to be possible to use these counters to measure
the momentum of single muons with a resolution of better than 4 MeV/c and systematic error of
< 3 MeV/c. Following earlier tests, the Electron Muon Ranger (EMR) detector was completed,
providing final results on the pion contamination in the muon beam. The TA has in addition
allowed fruitful exchange of information and experience among users.
WP7 (High Field Magnets): to mitigate the high risk of this novel Nb3Sn high field magnet
model development, additional steps have been introduced, leading to a revised calendar. The
mechanical structure of the magnet has been
completed and tested at LN2 temperature, the
coil tooling has been delivered and a test coil
with Cu conductor manufactured. Nb3Sn
strand for one magnet is delivered, the cable
designed, showing less than 5% degradation,
well within the specification.
The HTS insert magnet components are
procured and the YBCO conductor being
delivered. A test coil was constructed and is
being tested. The insert will be finished by end
of 2013.
For the HTS link two cabling machines were
and used. The HTS link construction is
finished.
Two helical undulators were built and one was
tested at LASA where problems indicated the
need for important design modifications.
For the support task the design and construction of all the cryostats and tooling for the irradiations
and sample tests have been completed. The irradiation of all the electrical samples and half of
the mechanical samples has been completed and conclusions on the suitability of insulation
materials have been formulated. The thermal studies have
been completed and HeII cooling models were produced.
WP8-Collimation and Materials managed to finish its main
deliverables ahead of schedule. In this reporting period the
emphasis was the investigation and characterisation of novel
materials for accelerator and collimator applications.
Previously irradiated samples where characterised.
Irradiation tests with novel materials could be done at GSI
and the HighRadMat facility established within the EuCARD
framework. The successful tests lead to the use of these
materials in test collimators for the LHC even beyond the
scope of this project.

WP9-NCLinac concerns a number of studies relevant for Linear Colliders (LC) presently
considered as future energy frontier
machines. Focused on the Compact Linear
Collider (CLIC) study it treats high-gradient
normal-conducting accelerating structures, in
particular their integration of these structures
in the so-called two-beam module and the
resulting limitations and constraints
concerning RF power and phase, breakdown,
higher-order modes, cooling, vacuum,
mechanical tolerances, alignment and
stabilisation and the overall integration. The
stabilisation and alignment question
addressed were treated using a quadrupole
mock-up, which could be successfully stabilized to the required nanometre level in a real
accelerator environment. These results are relevant for both normal-conducting and
superconducting RF based LCs. Also the solutions studied for the demanding beam diagnostics
for a beam delivery system (BPMs and LW), which were implemented and thoroughly tested at
ATF2 and PETRA3, are significant independent of the chosen technology. The exact control of
beam phase to precisions of below 0.01° (of 20 fs) is equally a problem for many future
accelerators, including linear colliders and light sources, but for large linacs it becomes even
more demanding, since phase information from very distant location has to be compared.
NCLinac has advanced this field both for the phase pick-ups as well as for the synchronisation
over long distances.
WP10 (Superconducting Radiofrequency technologies): The vertical electro-polishing setup
is completed and in use.
The proton linac cavities
are in the manufacturing
and test process shared
between the
manufacturers and the
research laboratories.
Delays at the
manufacturers will delay
the final tests by a few
months. The progress in
the LHC crab cavities has exceeded the goals of EuCARD, with the fabrication of a Nb crab
cavity. The CLIC crab cavity was fabricated and the LLRF for LHC and CLIC developed. Good
progress is achieved on magnetron sputtering, with high RRR values, uniform films and much
reduced deposition time. An EuCARD monograph was produced on sc RF technologies,
including aspects of thin films. The HOMBPM’s on the 3.8 GHz cavities was validated.
Modelling and experimental studies show however that, while the beam position can be
accurately extracted, the inverse field problem to identify cavity features from HOM signals is
very difficult; nevertheless, results obtained justify further investigations. The µTCA LLRF was
finalized, installed and tested at FLASH, already yielding a significant improvement of the field
stability. Two set-ups for GaAs cathode preparation showed contamination, and low quantum
efficiency after activation. Lessons learned allow an on-going development of a more advanced

state-of-the-art preparation system. A remarkable progress was the first FEL operation with the
SRF gun at ELBE in April 2013. The design of the automatic coupler cleaning has evolved, and
the studies allow a complete overview, including feasibility and cost.
WP11-ANAC (Assessment of Novel Accelerator Technologies) has provided its last
deliverable: a new concept for the LHC luminosity upgrade, based on flat beams, large Piwinski
angle and crab-waist, inspired by the DAΦNE upgrade, has been shown, quite unexpectedly, to
open new strategies to reach the goal of the LHC upgrade. This new approach requires further
studies to increase the particle stability. Non-
EuCARD work continuing the other tasks of
WP11 (DAΦNE, EMMA and emittance of
beams accelerated by laser-plasma) has further
consolidated the already provided EuCARD
deliverables.
EuCARD
management, beyond running the project, has continued its contribution to tightening links in
the accelerator community and creating sustainable collaborations. The concluding project
meeting was associated to a EuCARD workshop on visions for the future of accelerators and to
the kick-off meeting of EuCARD2, thereby drawing perspective for the immediate and farther
futures.

2. CORE OF THE REPORT FOR THE PERIOD: PROJECT OBJECTIVES, WORK PROGRESS AND ACHIEVEMENTS, PROJECT MANAGEMENT
2.1 PROJECT OBJECTIVES FOR THE PERIOD
In this final period of the project, the contractual objectives include the largest fraction of the
deliverables, as most tasks have the full project duration, while some shorter tasks were late. The
number of milestones naturally decreases, and many are lumped with their corresponding
deliverables.
The management (WP1) objectives have been mainly two-fold: i) create optimal conditions to
favour a successful termination both for the S/T studies and for a major reporting exercise: the
P3 periodic report (D1.3), over 40 deliverable reports for review at a learned journal level and
the final report (D1.4); ii) keep the momentum of the collaboration by attractive project events:
the third annual meeting (M1.4) and a conclusive meeting analysing the results and offering
perspectives (M1.5).
With a series of ambitious communication tools put in place in Periods 1 and 2 (web site,
publication portal, newsletters and monographs), the goals of the dissemination,
communication and outreach network (WP2) are to consolidate them and organize their
transmission to either TIARA or EuCARD2. Presentations on communication aspects, achieved
efficiency and future plans were the goals of the status reviews in two Annual Meetings (MS4,
MS5), with in view the final report summarizing the strategies and results (D2.1.1). The
deliverable foreseen on the use and dissemination of foreground turns out to be strictly redundant
with a chapter of the final report and will refer to it (D2.2.2).
The main goals of the scientific networks (WP3 and WP4) during this period are to finalize and
complete their activities: for WP3, this period is a key with the organization of
meetings/workshops in view of the production of three strategy documents that must meet the
consensus of the community: D3.1.2, D3.2.1 and D3.3.1 and serve as input to the update of the
European HEP strategy. For WP4 AccNet, the goal has been to actively continue the activities
of the three networks (M4.1.4, M4.2.4, M4.3.4) and prepare important deliverables summarizing
the network activities and results, putting forward the specific added value produced (D4.1.2,
D4.2.2, D4.3.3).

(WP6), which already had fulfilled its contractual obligation, the goal was to continue the open
access thanks to savings on EC resources and support from the STFC.
For most JRA tasks (WP7-11), the goal of task 1 of each WP has been to follow-up progress,
favouring technical exchanges by WP meetings, review meetings, or coordinator visits.
Reporting is an important aspect of these tasks. A number of milestones were attached to these
activities: M7.1.3&4, M8.1.3&4, M9.1.3&4, M10.1.3&4, except for WP11 that essentially
reached completion.
For WP7 (High Field Magnets), an essential goal is to reassess, with the support of its advisory
committee, the HFM program, schedule and take the steps to organize its full completion planned
after the EuCARD termination. All deliverables related to the model (studies and prototype) are
to be delivered: D7.2.1, D7.2.2, D7.2.3 and D7.3.1 . The WP will conclude as well on the HTS
insert fabrication (D7.4.1), on the construction of a 20m HTS link (D7.5.1) and on a prototype
of a Nb3Sn helical undulator (D7.6.1).
WP8 (Collimation and Materials) being ahead of schedule, it main goal in this period is the
documentation of a CERN deliverable (D8.3.1), and of the WP8 activity.
In WP9 (Normal Conducting Linacs), all milestones were met and the period objective is the
delivery of deliverables all scheduled for the project end (D9.1.1, D9.2.1, D9.2.2, D9.3.1, D9.3.2,
D9.4.1, D9.4.2, D9.5.1, D9.5.2). These deliverables include key aspects of the CLIC collider and
of common issues for ILC and CLIC colliders (RF cavities, geometric stabilization, ultrafast
synchronization, handling of very low emittance beams).
WP10 (Superconducting RF) is the largest WP in terms of number of tasks and deliverables,
funding and spectrum of research topics. Most of its milestones were met in the preceding period,
and all its deliverables except one are to be delivered during P3: D10.1.1 (data handling); D10.2.1
(super-conducting elliptical proton cavities); D10.3.1&2&3 (LHC and CLIC crab cavities,
LLRF for both); D10.4.2&3&4 (aspects of thin film cavities); D10.5.1&2 (use of HOM signals
as beam and cavity diagnostics; D10.6.1 (advanced LLRF for FLASH); D10.7.2 (higher yield
photocathodes); D10.8.1 (automated coupler processing).
WP11 (Assessment of Novel Accelerator Concepts): All other objectives having been met in
Period 2, the only deliverable remaining is D11.2.2.
These objectives of Annex 1 have been complemented by additional objectives in the interest of
the project and to consolidate the accelerator R&D community. They are discussed in the
description of the work progress and the management results.
2.2 WORK PROGRESS AND ACHIEVEMENTS DURING THE PERIOD

1.1.1. WP1: Project management
Please refer to Section 2.3.
1.1.2. WP2: Dissemination, Communication and Outreach (DCO)
The mandate of the Dissemination, Communication and Outreach (DCO) Work Package is to
establish and maintain efficient communication inside the consortium and enhance the
dissemination and outreach outside the consortium towards the scientific community and
beyond. The WP includes two tasks:
Task WP2.1: Coordination and communication,
Task WP2.2: Dissemination and Outreach
1.1.2.1. Task WP2.1: DCO Coordination and communication
Progress towards objectives
The main objectives have been to ensure an effective flow of information within all the Work
Packages, between WP2 and the Management and throughout the whole project. In this period
the DCO team organized 3 face-to-face meetings and 1 video meetings of the DCO team.
The DCO deputy coordinator is also an active member of project coordination meetings in order
to report DCO matters to WP1 Project Management. A network of WP DCO liaisons was
continued, to maintain a clear, two-way communication channel between WP2 and other WPs.
Synergies with other related accelerator projects were further developed and formalized in
Period 3 with the launch of the joined newsletter, Accelerating News1. Due to the newsletter,
EuCARD DCO team has combined efforts with TIARA, HiLumi LHC, EUROnu and CRISP.
For further details, see Section 1.1.7
Contractual milestones and deliverables
The deliverables due in this period (D2.2. and D2.3) have been achieved. The M9 milestone due
in this period has also been achieved.

Policy events and surveys
The Project Coordinator and administrative manager attended several meetings with EC officials
to discuss project related accelerator R&D topics, strategy in Horizon2020. The Coordinator also
attended and represented the project at the International Conference on Research Infrastructure
(ICRI 2012) conference. He also contributed to the “Consultation on possible topics for future
activities for integrating and opening existing national research infrastructures” issued by the EC
and initiated a coherent response from various branches of the community. The assessment of
this survey2 (published in February 2013) placed the topic of Accelerator R&D in a prominent
position.
Accelerating News (formerly EuCARD Newsletter)
During the period, the EuCARD newsletter was replaced by the Accelerating News, a
collaborative newsletter aimed at the accelerator community. The Accelerating News - first issue
was published on 24 April 2012- is a combined newsletter taking advantage of the synergies
formed between EuCARD and other accelerator projects cofunded by EC FP7. Four projects
were initially part of the newsletter: EuCARD, HiLumi LHC, TIARA and EUROnu. When the
EUROnu project finished in September 2012, the CRISP project was added to the newsletter.
The scope of the Accelerating News was extended over P3: it now covers a larger variety of
fields and targets a wider audience, also in some cases covering accelerator related topics from
life sciences. The number of subscribers rose from 800 to 1046, attesting to the success of the
new format of the newsletter. In order to further improve the Accelerating News, a survey3 was
conducted online and it received positive answers. The newsletter was also used to advertise the
EuCARD monographs, which led to a dramatic increase in orders from all around the world. The
Accelerating news will be continued under TIARA-PP and EuCARD2.
Figure 16: The six issues of the “Accelerating News”, with the first issue published 24 April 2012. The issues from
the EuCARD newsletter are still available in archives.

EuCARD-related Doctorates
46 Ph.D. theses were identified as associated to EuCARD during the whole duration of the
project. The WP leaders were made aware that the Ph.D. theses may be published as EuCARD
booklets. A number of Ph.D. theses related to EuCARD were published in the Monograph Series.
Due to different formal regulations concerning doctorate promotion processes at the European
universities, not all of the relevant theses were published in the Series. They were however
published by the relevant university press. Many of the project related theses are not yet finished.
They will be continued with EuCARD2.
EuCARD publication portal
A user-friendly publication portal is in operation. It has a customized interface of the existing
CERN Documentation System: the publications can be browsed against the type, kind, source
and work package. It automatically handles the needs of the refereeing system, depending on the
type of publication. As of 30 August 2013, the publications logged in the database amount to –
numbers in upper row of the table, but the increase in these numbers for P3 period are shown in
the lower row:

This large number of publications and oral presentations continues to shows the dynamism of
the project. The management of EuCARD continuously favours open access publications and
journals.
EuCARD Monographs
Seven additional EuCARD monographs have been published in Period P3 (reaching 18 volumes
in total). The monographs are also publicly available via the CDS database. Before distributing
to the partner libraries worldwide, IP and copyright issues have been investigated properly.

During the final Annual Meeting of EuCARD and kick-off meeting of EuCARD-2 the editor had
many discussions with the Conference participants concerning the support of this action, and the
interest in this sort of fast but strictly peer reviewed, and nicely printed publications, with ISBN
number. The series will be continued and the relevant discussion will also be continued within
the EuCARD2. The editor sent a few copies of full sets of these monographs to science and
technology financial decision makers with a very positive, even surprisingly positive, response.
A few meetings at the Nat. Ministry of Science and Education, and Ministry of Infrastructure
followed, with possible infrastructural consequences in the future.
DCO coordinator sent out approximately 250 copies of the monographs, separately from the
numbers of copies managed by CERN. These were sent to local libraries at around 20 universities
and the rest went to individual researchers.

1.1.3. WP3: Structuring the accelerator neutrino community (NEu2012)
NEu2012 offers a platform for consolidating the European neutrino community and enhancing
collaborative work and exchanges in view of delivering at the end of 2012 an agreed programme
of neutrino experiments, based on upgrades of existing infrastructures and/or on the proposal of
a new one. WP3 includes 3 tasks:
Task WP3.1: Coordination and communication
Task WP3.2: Getting the most out of existing neutrino facilities
Task WP3.3: Roadmap to the next European accelerator neutrino facility
1.1.3.1. Task WP3.1: Coordination and Communication
Progress towards objectives
The coordination of the WP activity continued by steering meetings and by frequent contacts
among coordinators. They focused on the successful organization of the third annual meeting of
the network (ie the 2nd EU Neutrino Strategy Workshop in May 2012) and on the effort to
assemble its last final road map deliverables.
Discussions with managers of projects closely related to NEu2012 (LAGUNA-LBNO, EUROnu,
IDS-NF as always and now CENF, ESS neutrinos and more) became even more frequent. The
program committee of the Strategy Workshop represents indeed all these components. This
included recently participation to the last EUROnu meeting June 2012, the most recent
LAGUNA meeting in Desy Feb 2013, the most recent IDS-NuFact meeting in RAL Apr 2013
and to the meetings of emerging proposals as NuSTORM (late March 2013) and of an ESS
powered neutrino Superbeam (May 2013).
Dissemination for WP3 remained an important area of work. WP3 steering committee members
were present in many international workshops with plenary and parallel talks confirming the
international visibility of NEU2012 and of the neutrino activities in Europe. The coordinators
were all on the program committee of the international NuFact12 workshop.
Monitoring developments in our research sector also remained very important. The sin213
reactor results in China, Korea and France in Spring 2012 confirmed the hope that CP violation
measurements were possible and called for. They are possible only with long baseline accelerator
neutrino experiments, more than ever a vibrant sector, in spite of all our EU difficulties, those
encountered in US for the approval of the Fermilab project (LBNE) or expected in Japan for their
new T2HK enterprise.
Contractual milestones and deliverables
The M48 milestone (fourth and last WP3 annual meeting) was cancelled, after all WP
deliverables were produced (D3.1.2, D3.2.1 and D3.3.1). Convening the community appeared to
be more appropriate in autumn 2013 after the final formulation of the HEP Strategy and a better
definition of its impact on the community.

1.1.3.2. Task WP3.2: getting the most out of existing neutrino facilities
Progress towards objectives
During the reference period the CNGS neutrino beam facility at CERN had its final year of
operation. The facility successfully concluded a cycle of seven years of operation since its start-
up in 2006. In the end 1.8×1020 protons were delivered on target, corresponding to about 80% of
the estimated beam intensity in the approved program. At the same time, the Grand Sasso
experiments advanced in their analysis and the OPERA collaboration announced the discovery
of two more ντ appearance events, thus making three in total, compatible with the expectations.
In the graph below the evolution of the integrated beam intensity for CNGS is shown.

In 2012, a lot of studies, specific instrumentation and measurements were done to better
understand the timing structure of the beam, such to undoubtedly resolve any issue or source on
the CERN side of errors that may contribute to the miscalculation of the beam timing.
The experience gained by the operation of this high-intensity beam facility over the seven years
from 2006 to 2012 is a very important asset for CERN and Europe. Supported by Neu2012
meetings and discussions occurred in 2012 to prepare the input for the European Neutrino
Community to the Strategy Upgrade Process. The submitted papers included both physics
experiments and schemes for possible upgrade of the CERN accelerator complex towards a next
generation neutrino beams.
In particular, the possibility to provide a higher-intensity proton beam up to 750 kW was outlined
as well as the required R&D program to achieve it. The table below indicates the SPS potential
to provide CNGS-type beam for neutrino facilities after implementation of the LiU upgrades.

The detailed studies are on-going within the LAGUNA-LBNO EU/FP7 Design Study,
addressing SPS but also its injectors in particular PS.
Two scientific proposals were submitted to the SPSC in 2012. The first, from the LBNO
collaboration, describing a staged approach for a CERN-based long-baseline neutrino beam from
CERN to a far detector located at the Pyhasalmi mine in Finland at 2300 km distance. The second
is a combined proposal from the ICARUS and NESSiE collaborations for the study in a short
baseline in the North Area with detectors at 460 and 1600 m distance.
As starting stage for this new generation of beams, the concept of a Neutrino Test Facility in the
SPS North Area is considered to create a neutrino detector R&D area where detector prototypes
could be exposed simultaneously to a neutrino beam and low-energy charged beams of (e, u, û).
The physics reach and performance of the facilities has been the subject of several meetings
organized within EUCARD/Neu2012 and summarized in a one-day workshop organized at
CERN and in the Task 3 report.

plans of AccNet were reported. Since summer of 2012 AccNet-EuroLumi launched and
supported studies on various novel types of Higgs factories, such as circular e+e- colliders (LEP3,
TLEP), collider, a high-luminosity ep collider based on the LHC, as well as higher-energy
hadron colliders (HE-LHC, VHE-LHC), either in the LHC tunnel and in a new 80-100 km tunnel.
Presentations featuring and disseminating results of AccNet studies were given at various
occasions during this period, e.g. at invited seminars at Oxford, KEK, Frascati, Saclay, Orsay,
Sendai, CHIPP, oPAC workshop.
In total 25 AccNet mini-workshops and AccNet co-sponsored conferences were organized, e.g.
on LEP3 and TLEP (5 mini-workshops), on VHE-LHC, on SAPPHiRE, on electron cloud, on
LHC optics, on LLRF for X-FEL, on the use of C for industry and research, and low-level
RF for XFE, and on advanced acceleration concepts.
The AccNet web site was continually updated and enhanced. Budget and manpower plans were
also updated and adjusted.
Contractual milestones and deliverables
The final annual AccNet steering committee (M4.1.4) was held during the parallel sessions of
the EuCARD13 Annual Meeting. The AccNet Strategy for future proton & electron facilities in
Europe (deliverable D4.1.2) was published in the form of a report.

1.1.4.2. Task WP4.2: EUROLUMI
Progress towards objectives
The topical workshops were organized by EuroLumi either alone or in collaboration with EU
and non EU partners wherever relevant. Amongst important EuroLumi partners from outside
Europe are the consortium of US national accelerator laboratories US-LARP, the KEK
accelerator laboratory and Hiroshima University in Japan, and CINVESTAV Mexico. The goal
of the topical workshops typically was to assemble 30 to 40 world experts for brainstorming on
advanced topics. In most cases, the attendance exceeded this goal, demonstrating the added value
of this format of networking. In all workshops, the fraction of participants originating from
outside EuCARD was significant, typically 25%, sometimes above 50%. Events were often
organized at CERN in view of its numerous facilities, lower costs and easy air flight connections
to most world destinations, and since the main topic of EuroLumi – the LHC upgrade – is directly
linked to CERN.

Workshop 3, attended by the CERN Director of Accelerators & Technology as well as by the
KEK “trustee” in charge of strategy, was the first ever workshop discussing the possibility of a
circular Higgs factory in the LHC tunnel or in a new 80 or 100 km tunnel. It was followed by
four similar mini-workshops in 3-month rhythm (workshops 4, 6, 10 and 14), making rapid
progress on the accelerator design. Workshop 8 was the first ever event devoted to a low-cost
Higgs factory, and workshop 9 the first one devoted to 100-TeV pp collider in a new large tunnel.
Together these workshops developed a cost-efficient staged strategy towards delivering highest-
energy highest-luminosity collisions of various species to study the Higgs boson with the best
possible precision and to explore the closure of the standard model and to discover New Physics.
Workshops 1, 5, 7, 11, and 13 addressed important aspects of the HL-LHC design, the LHC
injector upgrade, and FAIR. Workshop 12 (“EuCARD13”) on the visions for the future of
accelerators was co-organized by WP4 EuroLumi. One example outcome of these workshops
was the stronger collaboration with the European space satellite community assembled around
ESA. Another was a novel technique of electron cloud diagnostics, developed by the CERN-GSI
collaboration in the framework of EuroLumi, by which the average electron cloud density around
a storage ring is inferred from the bunch-by-bunch synchronous phase shift. The ratio of
registrants/speakers is included to illustrate the dynamic interactivity. For comparison, at a
typical IPAC this ratio is ~12.

These workshops provided excellent opportunities to share experience among several fields of
RF technology, from low-level systems to solid-state power amplifiers.
More specifically, the 4th RFTech workshop covered a large range of RF topics, including C-
band RF, X-band RF, reliability, LLRF, RF diagnostics, reliability, costing, breakdown,
operation, klystron lifetime, and RF efficiency; and it also addressed RF issues for many
important present or planned accelerator facilities, e.g. SPIRAL2, MYRRHA/MAX, CLIC,
TESLA, ELI-NP, LHeC ERL, TLEP, LHC, FLASH, PS Booster, MedAustron, and SwissFEL.
Participants came from DESY, CERN, INF-INFN, TUD, UROS, GANIL, PSI, LPSC/CNRS,
UJF, TUL, and ISE-WUT.
RFTech also organized or co-organized several topical workshops related to low-level RF
control, as well as special sessions at the MixDes2012 Conference on Mixed Design for
Integrated Circuits and Systems with applications to accelerator RF systems, and at the ICAP’13
on accelerator RF related computing. Some RFTech experts also attended the IEEE Conference
workshop on Real Time techniques, RT2012, in June 2012.
An important result is a report on strategy/results for cavity design, LLRF & HPRF systems and
design integration, and costing tools.

1.1.4.4. Task WP4.4: EURONNAC
EuroNNAc – a European Network for Novel Accelerators looking at the Next Generation of
Novel Electron Accelerators – was launched in December 2010 on the EuCARD initiative.
Progress towards objectives
The second major EuroNNAc workshop was held at CERN, on 2-4 May 2013. It created four
task forces towards an EU-wide (or even global) coordination of advanced accelerators, defined
strategies and detailed plans for each task force, progressed towards a coherent proposal of one
or a few European and international pilot facilities for advanced accelerators; prepared a written
report on novel acceleration and the EuroNNAc network; approved plans for a European
conference for advanced accelerators (the first one EAAC2013), and prepared an input statement
to European Strategy for Particle Physics ("On the Prospect and Vision of Ultra-High Gradient
Plasma Accelerators for High Energy Physics").
EuroNNAc organized the first ever EAAC workshop, in Italy from 2 to 7 June 2013, with 145
participants. An important practical conclusion is that a substantial extra funding is to be found
to accomplish the EuroNNAc goal of a distributed European test facility.

1.1.5. WP5: Transnational access HiRadMat@SPS
HiRadMat (High Irradiation to Materials) is a new facility at CERN designed to provide high-
intensity pulsed beams to an irradiation area where material samples as well as accelerator
component assemblies can be tested. The facility uses a 440 GeV proton beam extracted from
the CERN SPS with a pulse length of 7.2 μsec, to maximum pulse energy of 3.4 MJ. In addition
to protons, ion beams with an energy of 173.5 GeV/nucleon and total pulse energy of 21 kJ can
be used. Over the reference period, the first HiRadMat experiments took place as scheduled and
successfully completed data taking in the beam period from May to November 2012. A detailed
list of experiments is online available at http://cern.ch/hiradmat (section experiments). These
first experiments included candidate materials and prototype assemblies of LHC collimators
foreseen to operate at the ultimate LHC beam powers, experiments on vacuum windows,
benchmarking detector and target material options for use in future high power proton beam
applications.
Figure 20: Photo of the HiRadMat experimental area. The primary beam line with its last equipment is shown on
the left. The three yellow base-supports for the experiments are visible at the centre, with one experiment already
installed in the middle one. The massive beam dump is visible downstream the beam path.
The beam conditions relevant to the experiments: intensity, pulse structure, focusing and spot
size possibilities, beam interlocks conditions etc. are defined and documented in the project web
page: http://cern.ch/hiradmat.
As HiRadMat@SPS is a high-intensity beam area substantial pre-cautions are necessary for the
access and operations with the users. For each experiment three phases are needed: a) preparatory
phase including experiment review by CERN safety officials; typically 6-9 months before the
experiment is scheduled, b) the preparation of the experimental setup outside the irradiation area
and subsequent installation using remote tooling to the area and the exposure to beam, and c) the
final removal of the equipment and inspection at the end of the experiment and some cool-down
period. TA funds were also used to cover the needs of the experimental teams in all three phases.
Table 1 lists the experiment schedule of 2012 for data taking with beam.

1.1.5.1. Description of publicity concerning new opportunities for access
Access to the HiRadMat facility has been publicised principally through web pages,
presentations at international conferences, complemented by targeted visits and emails to
potentially interesting communities and laboratories. The HiRadMat web pages, also accessible
through the EuCARD main web, give an overview and the capacity of the facility and provide
information on the rules and regulations for access. Conference presentations include workshops
on future Neutrino Facilities, high-power target development, the International Accelerator
Physics conference and EuCARD meetings. Visits to PSI and RAL laboratories have been
organized to present the facility and its potential.
1.1.5.2. Description of the selection procedures
The HiRadMat Scientific Board assesses the beam and TA requests, by inviting each team to
present the scientific goals, proposed installation and post-irradiation analysis of their
experiment. On positive recommendation by the Scientific Board a beam time slot for the
experiment on the yearly schedule is reserved. This beam slot is then validated after the
experiment is reviewed and positively recommended by the HiRadMat Technical Board
consisting of CERN beam experts and safety officials. The Scientific Board meets typically three
times per year, while the Technical Board upon needs.
Over the reference period the following board meetings took place:
23. April 2012 Scientific Board Meeting
15. June 2012 Technical Board Meeting
27. July 2012 Technical Board Meeting
28. September 2012 Technical Board Meeting
18. October 2012 Scientific and Technical Board Meeting
With the CERN accelerator shut-down beginning December 2012 until end 2014 no more
experiments are scheduled and board meetings were not required anymore.

Scientific output of TA-supported users at the facility
User meetings
Due to the special nature of the HiRadMat facility and the stringent conditions implied to the
experiments, mainly due to the induced radiation fields from the high-power beams, preparing
for experiments can be rather challenging. Therefore sharing of the information, on experimental
techniques and tooling is vital and heavily promoted to best use the TA funds. During the beam
time period until December 2012 user meetings were scheduled on a bi-weekly basis (Friday
afternoon). This was continued for a few weeks after the start of the CERN shut-down for de-
commissioning activities of the experiments.

1.1.6. WP6: Transnational access MICE
WP6 provides transnational access to a specialized beam line at the Science and Technology
Facilities Council (STFC) ISIS facility at the Rutherford Appleton Laboratory (RAL). This
beam line, together with its associated infrastructure, was originally referred to as the MICE
facility, but in order to distinguish the facility more clearly from the MICE experiment (see
below), the facility is now designated the Ionisation Cooling Test Facility (ICTF).
The ICTF provides muon beams of either sign, pulsed at 1 Hz, in the momentum range 120
MeV/c to 350 MeV/c, as well as protons, pions and electrons from 100 MeV/c to 400 MeV/c.
The intensity of the muon beam is ~50 particles per pulse. During P3 significant progress has
been made on the installations for the radio-frequency (RF) and Liquid Hydrogen (LH)
systems, which will complete the facility.
The ICTF has been developed in the first instance for the MICE experiment (Muon Ionisation
Cooling Experiment) http://mice.iit.edu/, which is the first experiment to be installed at the
facility. The MICE experiment will allow high-accuracy measurement of emittance, and will
deploy unique absorbers (using the Liquid Hydrogen) and re-acceleration stations (using the
RF) to assess the efficiency of ionization cooling.
1.1.6.1. Description of publicity concerning new opportunities for access
All available TA resources were allocated at the end of P2 (see P2 report), and so access to the
facility was not advertised further during P3.
1.1.6.2. Description of the selection procedures
As reported previously, all available TA funding was allocated just before the end of P2, so the
Selection Panel did not meet during P3.

A total of 1107.7 transnational access units (beam-hours) were used during period 3.
Scientific output of TA-supported users at the facility
TA-supported users have made wide-ranging contributions to the scientific output from the
facility during P3.
The scientific goals of MICE depend on the measurement of the beam emittance, using a single-
particle method. The Time-of-Flight (TOF) counters have been essential both for identification
of the beam particle and, prior to the availability of magnetic spectrometry in 2015, for
momentum measurement. Thanks to the outstanding performance of the TOF counters (see also
P2 report), it has proved possible to use these counters to measure the momentum of single
muons with a resolution of better than 4 MeV/c and systematic error of < 3 MeV/c. The ability
to measure the longitudinal momentum, pz , to this precision will complement the momentum
measurement of the magnetic spectrometers. For low transverse amplitude particles, the
measurement of pz in the TOF counters is expected to have better resolution than that of the
spectrometers, which are primarily designed for measuring the transverse component of the
momentum.
The performance and operation of the TOF counters has been one of the principal goals of the
TA-supported groups, in P3 as well as in P1 and P2.
Figure 21and Figure 22 (taken from http://arxiv.org/pdf/1306.1509v1.pdf) show the measured
horizontal and vertical emittances, compared to simulations. These results demonstrate that the
beam emittances are highly suitable for the MICE experiment

1.1.7.2. Task WP7.2: Support Studies
Progress towards objectives
Task WP7.2 consists of two sub-tasks:
Sub-task WP7.2.1 (Radiation resistance certification for coil insulation and
impregnation): detailed specification of irradiation at LN2 temperatures, start of
irradiation of samples, determination of mechanical properties measurements, design of
the cryostat for electrical certification measurements at LN2 temperature
Sub-task WP7.2.2 (Thermal models and design): thermal measurements of the un-
irradiated samples, development of steady state and transient thermal model of the
magnet coil, determination of the safe heat load to the magnet coil, cool-down time and
cryogenic system cooling capacity.
Sub-task WP7.2.1 Radiation resistance certification for coil insulation and impregnation
A first series of irradiations at National Centre for Nuclear Research (NCBJ), Swierk, Poland on
the thermal samples was concluded in June 2012 but due to the high dose rate the samples are
not usable due to too large radiation damage. Tests were done to understand this excessive
damage and solutions were found by reducing the dose rate by a factor of two and some cooling
improvements. It was decided to re-schedule the irradiations of the samples such that the ones
with the shortest irradiation times will come first: the electrical samples first, followed by the
mechanical samples and then the thermal samples. At present the irradiation of the electrical
samples and half of the mechanical samples has been completed. The equipment for the
cryogenic electrical and mechanical characterisation tests, e.g. the cryostats, high voltage
equipment and traction equipment was designed, constructed and commissioned. The irradiated
mechanical and electrical samples and the non-radiated reference samples have all undergone
their characterisation tests. A deliverable report was produced in June 2013 and submitted in
July 2013.

Sub-task WP7.2.2 Thermal models and design
The deliverable 7.2.3 “Superfluid helium transport model for the thermal design of the high field
model magnet” was produced in May 2013. This deliverable covers the work on the construction
of a new numerical finite element model using a simplified formulation of the two-phase theory
for superfluid He for accelerator magnets.

1.1.7.3. Task WP7.3: High Field Model
Progress towards objectives
During the period, 23 meetings of the Magnet design working group were held. Furthermore an
External Scientific Advisory Committee (ESAC) review was held in February 2013.
The ESAC review committee acknowledged the progress made and the maturity of the
project. It recommended to carefully get confirmation of the validity of each step of the
construction. It insisted on the need for a test with one or two (out of 4) coils to validate
the concept of flared-end coils.
The strand procurement progressed well and at the end of the period enough strand had
been delivered to construct one full set of coils for the dipole.
The cable for the dipole was developed and the cable design is valid for both PIT and
RRP conductors, which are being procured. The degradation of the critical current due to
the cabling process is less than 5 %.
The mechanical design is complete and the magnet structural components have been
procured and delivered. The structure was assembled with dummy Al pieces in place of
the coils and extensively instrumented with strain gauges. This ‘dummy’ magnet has been
tested at liquid N2 temperature in a purpose-built installation at CERN to verify the
detailed mechanical behavior under cool-down.
Detailed models of several types have been made to calculate the quench protection cases
of the dipole. The conclusion is that the magnet can be protected with a comfortable

margin even in the case of a quench starting in a low field region. A maximum hot-spot
temperature of 140 K can be achieved in a worst-case scenario.
The test facility for the LHe test of the dipole has been designed. The outer vacuum vessel
of the cryostat has been ordered and the delivery is foreseen for summer 2013. The
tendering procedure for the inner He vessel Cryostat has been started and this component
is expected for delivery by June 2014. The cryogenic components (eg. valve boxes and
transfer lines) and the cryogenic controls racks and test instrumentation racks are in an
advanced state of detailed design and will be ready in summer 2014. The test station will
be installed in the CERN vertical tests station in building SM18 where the pit for the
cryostat, the power supply and other auxiliary equipment already exist.
A complete design report has been written. The report covers the electromagnetic and
mechanical design of the magnet, the quench protection, the tooling design, the coil
manufacturing and the assembly procedures. The design report is part of the deliverable
for this task.
A coil of the 3-4 type with Cu conductor has been wound with the final tooling. A small
modification of the reaction tooling will be implemented at the end of the summer after
which a few turn superconducting test coil will be wound and reacted to test the
procedures.

The main deliverable (7.3.1 at M48) was rescheduled as more tests and intermediate steps were
introduced to consolidate the design and manufacturing steps of the dipole magnet and due to
the delays in the construction of the test station. The deliverable report can nevertheless be
produced in 4 parts describing the main design and construction steps. This comprises of
Part I: Design report for the dipole magnet
Part II: Dipole magnet structure tested in LN2
Part III: Nb3Sn strand procured for one dipole magnet
Part IV: One test double pancake copper coil made
The magnet with a single superconducting coil will be tested in September 2014 in the new
CERN test station. The completion of the Fresca2 magnet is now part of the CERN and CEA
core activities as it is essential for the development of high field magnets for future proton
colliders and is therefore guaranteed.

1.1.7.4. Task WP7.4: Very high field insert
Progress towards objectives:
This last period was mainly devoted to finalize the mechanical design of the dipolar insert, to
finalize the drawings and to launch the orders for all tooling and mechanical part, to order the
conductor and to prepare the final tests.
The design report for the dipolar insert was produced in May 2013. It contains the
following chapters: insert magnet configuration, conductor definition, magnetic study
with the outsert, protection, mechanical structure, assembly, HTS test solenoids. The
report is the object of the deliverable D7.4.1, part I
Protection studied for the 2 magnets powered together: this point is quite important, many
simulations were done with different codes. If the protection of the insert alone is not a
problem, the problem is more crucial when the insert will be powered inside the Fresca2
dipole. It is unclear how high hot spot temperatures can be tolerated in an YBCO coil and
when does the delamination of the conductor really occur. It is expected that a lot of
information will be gained from the tests of the magnet.
Order and delivery of the conductor: the core YBCO conductor was ordered in December
2012. Its delivery is expected in September 2013, with some delay showing the technical
problems when increasing the unit length of YBCO tape

Study and ordering of mechanical parts: all the studies for the mechanical parts for the
windings and for tooling were finished in June 2013. All the orders were passed until
beginning of July. Delivery is expected until November 2013 (Deliverable D7.4.1, part
III). Realization of a prototype and preparation of its test: a single pancake prototype was
wound at Saclay in July 2013, and has been sent to Grenoble for testing in September
2013. In parallel, a test facility has been prepared to test this insert in a 10 T external field
at Grenoble. A particularity is that it will be possible to change the orientation of the
pancake in the external field to study this effect on the conductor critical current (D7.4.1,
part II).
Figure 25: Cross-section and 3D model of the insert
The protection of the HTS insert remains an issue due to the very low propagation velocities and
the high current densities. The very large magnetic coupling (0.9) with the outer Nb3Sn dipole
makes the protection more difficult. From the study of different quench scenarios we conclude
that a fast discharge of both magnets is mandatory. Another simulation work, based on finite
element codes, gives the space and thermal evolutions of the hot spot. They confirm the very
slow development of the normal zone with two consequences: the difficulty to detect a quench,
and high mechanical stresses due to differential thermal contraction. Highly instrumented coils
with different characteristics (Cu quantity, insulation) have been made to verify these
simulations.
HTS insert, interface with the Nb3Sn dipole
The design of the HTS insert dipole has been studied in detail with 3D electro-magnetic and
mechanical models. The insert will be mechanically independent from the Nb3Sn dipole. The
insert supporting structure is a 3 mm thick stainless steel tube. The magnet is composed of six
flat pancakes wound with a 12 mm wide YBCO conductor.
The conductor is made of two tapes soldered together with a Cu tape. This configuration should
meet the numerous requirements such as mechanical performance, protection, industrial
realization, AC losses etc.. A first length was produced by the tape manufacturer and will be
tested. To get a nominal insert field of 6 T insert with a current of 2800 A two conductors will
be put in parallel with transposition from pole to pole for a balanced current distribution. Central
iron poles are added to reduce the peak fields. A mock-up with dummy Al coils has been made
with the iron poles, the steel pad and the external tube. The pad is machined in two parts and will
be welded together. The external tube will be shrink-fit around the pad.

Technological implementation, First YBCO solenoids and pancakes
To proceed step-by-step towards a dipole insert of HTS conductor, several HTS solenoid coils
have been made and tested up to their limits in existing high field facilities at partner’s labs. Only
YBCO coils have been realized, as this was the chosen conductor. Tests have been carried out
and protocols have been defined to make low resistance (40 nΩcm2) and reproducible
connexions between YBCO tapes.
In Grenoble, a double pancake carried a current of 400 A at 4.2 K under 18 T before the tape
broke close from a current lead. The engineering current density was 1000 MA/m2 and the hoop
stress overstepped 700 MPa. Another double pancake was tested in Karlsruhe, and showed very
similar results: the breakdown occurred at a hoop stress of 730 MPa, but under 10 T and 700 A
.
In conclusion, after several YBCO coils made with low performance, new coils, both layer and
double pancake type, were successfully made, with a performance close to the conductor intrinsic
limits. Those are higher than the values in the designed YBCO insert.

1.1.7.5. Task WP7.5: High-Tc superconducting link
Progress towards objectives
The superconducting link task developed and built a 20 m long Superconducting Link made of
HTS (High Temperature Superconducting). Following an intense R&D activity, which included
the study of novel concepts of cables made from HTS tape conductor and the development and
test of prototype units, the final deliverable was successfully assembled at CERN in May 2013.
A five-meter long Superconducting Link containing 25 Twisted-Pair MgB2 cables was
assembled at CERN and successfully tested at the University of Southampton. More
recently, a dedicated campaign of tests was launched at the University of Southampton
with the objective of studying the performance of the cables in case of resistive transition.
Transient behavior in He gas environment was studied.
Following the successful validation of prototype cables, two novel cabling machines
were developed and assembled at CERN. These machines enable respectively a) the
controlled production of long -kilometer length- electrically insulated stacks of tapes and
b) the final twisting and electrical insulation of two stacks of tapes to produce the final
Twisted-Pair unit. The process is applicable to MgB2, YBCO and Bi-2223 conductors
[2].
Twenty-five Twisted-Pair cables, each containing three MgB2 tapes and four copper
strips, were made at CERN using the newly developed cabling machines. The 25
Twisted-Pair cables were then assembled together to form the 20 m long final multi-cable
assembly. The multi-cable assembly was found to have the originally estimated
geometrical characteristics (about 40 mm external diameter when MgB2 tapes are used)

and a minimum-bending radius of about 1 m. Each Twisted Pair cable in the assembly is
able to transfer 2×±1 kA at 30 K and 2×±2 kA at 20 K
A 20 m long Nexans line with dimensions optimized for hosting the multi-cable assembly
was procured by CERN. A novel test station, which integrates this line has been designed,
constructed and fully commissioned at CERN

1.1.7.6. Task WP7.6: Short period helical superconducting undulator
Progress towards objectives
After the selection of the Supercon Nb3Sn wire (see previous periodic report), much of the work
was devoted to the preparation, realization and tests of 2 similar 300 mm long helical undulators.
For the construction of the 2 undulators the former manufacturing steps were modified for
minimizing the risks of failure. A method to alumina- coated the former was developed and
qualified. The vacuum impregnation method was also qualified. Finally, the two undulators were
realized during Q4 2012 at STFC-RAL.

The test of one undulator was done at LASA. For this an agreement was found with INFN-LASA
laboratory to test the two undulators in their laboratory during Q1 2013. The results were quite
disappointing: one undulator had a very high resistance (broken wire) and could not be tested.
The second one had quenches well below the nominal, and a resistive part was detected on it.
Nevertheless, magnetic measurements were performed at low current. The cause of these
problems was later identified as a break in the conductor. Also, the fractured macor winding
posts indicate that significant tensile force was present in the windings at some stage of the
realization.

Task WP9.3: Linac and final-focus stabilization

1.1.9.1. Task WP9.1: Coordination and Communication
Progress towards objectives
The coordination between the different tasks has been smooth and natural. Areas that required
some effort were the coordination between task 9.2, looking at the CLIC high-gradient
accelerating and decelerating structures as part of the two-beam module (TBM) with all its
aspects of mechanical precision and tolerances, cooling and temperature control, stability and
the integration into the tunnel, and task 9.3, addressing the linac alignment and in particular the
investigation possibility to align stabilize of a main beam quadrupole mock-up, which of course
is also integrated with the TBM.
The coordination and communication activities also included the organization and planning of
the annual meetings and here in particular the parallel sessions and the satellite meetings, in
which the annual reviews were performed and which gave the possibility to bring representatives
of all tasks together face to face. This was done both in Warsaw in 2012 (see
https://indico.cern.ch/conferenceTimeTable.py?confId=166908#all.detailed) and at CERN in
2013 (https://indico.cern.ch/conferenceTimeTable.py?confId=234798#all.detailed). We
reported in detail on the progress of NCLinac on these meetings, complemented by highlight
talks on selected topics (2012: “Feedback performance, precision alignment and nanometer scale
stabilization of CLIC magnets” by A. Jeremie and “CLIC RF structure precise assembly and
thermo-mechanical modeling in CLIC” by K. Österberg, 2013: “Understanding the breakdown:
new prospects?” by F. Djurabekova and “Linac stabilization” by K. Artoos). Both these meetings
were at the same time used to prepare EuCARD-2, in which parts of NCLinac will find a logical
continuation (in 2 tasks in its work package 12, “RF Technologies”). Initiated also by the
excellent results of NCLinac’s work package 9.3, a special FP7 proposal for an initial training
network on metrology and alignment was very successfully rated and has now started
(http://pacman.web.cern.ch/pacman/). The highlight talks and the contributions by the different
partners to the EuCARD Newsletter, which later became the “Accelerating News”
(http://www.acceleratingnews.eu/) was the outreach created by NCLinac.
With the coordination and communication between the tasks of WP9 well established, but also
with excellent coordination inside EuCARD as a whole and in fact with the other active FP7
instruments in the field of accelerators and accelerator physics (HiLumi-LHC, TIARA,
EuCARD-2), NCLinac brought forward the field quite significantly, reflected also in the quantity

1.1.9.2. Task WP9.2: Normal Conducting High Gradient Cavities
Progress towards objectives
Double-length PETS – CIEMAT has successfully completed the design, assembly and test of
the first double-length PETS for the CLEX module. The design comprises eight identical copper
bars with damping material and two compact couplers placed at both ends of the bars to extract
the generated power. The first PETS unit was fully assembled (see Figure 31) and tested at low
power. The compact couplers were successfully brazed and electro-beam welded to the so-called
mini-tank. The geometrical control of the eight corrugated copper bars as well as of the compact
couplers was within specification. The measurements were cross-checked and confirmed at
CERN. For the RF characterisation, a dedicated system to measure the S-parameters was
developed by CIEMAT (see Figure 32 and Figure 33). The power transmission efficiency was
obtained by placing between the couplers several copper rings with different lengths
(corresponding to 0°, 60° and 120° phase advance). No significant de-tuning was observed. A
second PETS unit is currently under fabrication and planned to be completed in December 2013.
New companies have been qualified for this production.

HOM damping – The UNIMAN collaboration is focused on a linac consisting of 26-cell
structures providing a 100 MV/m accelerating field and ensuring sufficient wakefield
suppression by interleaving different structures. The design for a 6-fold interleaved structure is
complete. Following a pre-series phase validated at CERN, the production of the entire structure
has been launched at Morikawa in Japan. The dimensional control of the disks and the
preliminary RF results (see Figure 34 and Figure 35) showed that the disks were acceptable and
that the structure could be tuned to reach the specification. Indeed, only few m errors have been
observed. The assembly consisting in bonding the disk stack and brazing the couplers onto it has
been completed. The cooling circuits will be brazed in September and the RF measurements and
tuning will follow. The structure is foreseen to be tested at high power in the year 2014.
A new cell design has been studied. It features improved overall wakefield suppression and
exhibits a larger 1st dipole bandwidth. An improved HOM coupling from cell to manifolds is
also proposed together with a reduced H-Field value on the cavity walls.

breakdown in accelerating structures. One of the key findings is that dislocations are activated
in the near-surface region of accelerating structures during its operation by the stress. These

dislocations can contribute strongly in nucleating of rough features, which at a later stage can be
further enhanced by long-term processes such as, for instance, surface diffusion enhanced by
electric field and electro-migration due to high field emission currents. However, the studies
show that a void buried under the surface can initiate the self-reinforcing growth of a protrusion,
if a high electric field is applied to the surface (see Figure 36). This mechanism can be seen
experimentally in the catastrophic growth of field emission currents, measured in the DC setup
at random spots on a seemingly flat surface. These features (field emitters) on a nanometre scale
may lead to breakdown events, giving a possible resolution of the long-standing mystery of
vacuum breakdowns in the absence of sharp surface features.
Figure 36: Simulation of the creation of a protrusion
from a void due to stress
Figure 37: Fits of the breakdown rate as function
of the accelerating gradient
This mechanism is confirmed by the analysis of crater features seen in the high resolution
scanning electron microscope images of spots of breakdown damage.
At a different scale, an analytical model based on thermodynamic consideration of formation of
extended defects in thermodynamic equilibrium gave a solid ground to the experimental
measurements of breakdown rates versus accelerating gradients. The experimental data could be
fitted with comparable quality to the existing empirical fits (see Figure 37), however providing
a physical interpretation to the fit parameters, such as the formation energy to create a dislocation
or void and the volume change due to this dislocation. Moreover, the prediction of this
dependence to be non-linear with decrease of the value of the gradient was confirmed later on in
the experiments conducted at CERN.
A hybrid electrodynamics/molecular dynamics model with the focus on the electronic dynamics
has been developed. The Joule heating of thin protrusions leads to the evaporation of atoms,
assisted by the applied field. This comprises a neutral component necessary for plasma
formation. The results of a 2D particle-in-cell calculations show the necessity of greater flux of
neutral atoms for the plasma to develop until a sustainable stage. The existing 2D particle-in-cell
model was refined to increase the resolution near the source of the neutrals (a tip). This led to
the result indicating the possibility of full small plasma development close to the tip; the plasma
ions sputter the surface at the early stage of full plasma build-up, feeding back the developing
plasma.
Diagnostic equipment – The upgrade program of the two-beam test stand continued with the
installation of the flashbox (see Figure 38). Signals of breakdown were recorded and analysed.
A program was developed to increase the sensitivity of the probe beam position monitors. The
piezo-motor driven stage to investigate in-situ discharges inside an electron-microscope has been

improved continuously and now permits scanning. Tests have been conducted on different
samples, which were then cut to investigate the presence of voids (see Figure 39).
Figure 38: Installation of flashbox in the two-beam test stand
Figure 39: Observed sub-surface voids
Precise assembly – UH continues the study on the high-precision assembly of RF structures and
several activities are on-going in parallel. The FE model of the two-beam module (see Figure
40) has been remarkably improved. In addition to the gravity, vacuum and RF loads, the
environment conditions (see Figure 41) have been added allowing thus to simulate the thermo-
mechanical response of the module following different ambient temperatures (from 20 ℃ to
40 ℃) and air speed (from 0.2 m/s to 0.8 m/s). The tests on the first module prototype (see Figure
40) started in January 2013. Several CLIC operation conditions have been tested by gradually
heating the different module components. In addition, by measuring the position of the fiducials
on the RF structures with the laser tracker Leica AT401, the alignment of the beam axes is also
derived. At the same time the temperature of the RF structures is monitored and recorded
throughout the tests by means of the sensors attached to them. The experimental results are in
good agreement with the model. Figure 41 shows the measured and predicted transient thermal
response of the accelerating structures by changing the ambient temperature from 20 ℃ to 30 ℃;
to be noted that the experimental transient time, almost twelve hours, is in agreement with the
results of the numerical modelling.

1.1.9.3. Task WP9.3: Stabilisation
Progress towards objectives
A prototype of the final mechanical guidance housing the actuators of the CERN stiff
stabilization system (see previous periodic report for unprecedented stabilization results) further
improved the resolution of the positioning and nano-metrology and increased the lateral stiffness
by a factor 500. A final mechanical design was made for a CLIC Main Beam Quad type 1 (100
kg, 0.5 m) and type 4 (400 kg, 2 m) based on aluminium profiles and plates (Figure 44). Supports
for the alignment sensors and the interface with the alignment system were also included in the
design.
Figure 44: a) Stabilisation system MBQ type 1 b) cut-away view with inclined actuators
A test bench representative of the stabilisation system (Figure 45) was built in order to house
several means to measure the relative displacement of the test mass. This allowed a comparative
study between strain gauges in the actuators, the voltage applied to the actuators, capacitive
gauges, a triple beam LASER interferometer, a broadband seismometer and an optical linear
encoder.
For the pre-alignment system, all the upgraded cam movers were validated successfully on a 1
DOF mock-up. Repeatability below 1μm was obtained throughout the whole measurement range
of 10 mm, and below 0.3 μm was over a reduced stroke of ± 3mm.

A 5 DOF mock-up was built for the final validation of cam movers and installed in one of the
most stable places at CERN. It consists of an instrumented rigid chassis, on which additional
loads can be put, installed on 5 cam movers. A mechanical system blocks the 6th degree of
freedom, along the longitudinal Z axis (Figure 46). The following results were obtained:
Movement resolution below 1 μm everywhere in the displacement range, repeatability below 5
μm for the two translation axes (X and Y), and below 5 μrad for the roll (rotation around the Z
axis), the correct position was found in 3 to 5 iterations without additional load (more iterations
were needed when load was added), displacement accuracy depends on the length and
complexity of displacement for example displacements accuracies are in the order of 10-20 μm
and μrad for the first iteration in case of simple movements.
Figure 46: 5-DOF mock-up coordinate system
These results showed that the type 4 cam mover based system meets precision requirements
using an iterative process. A more compact cam system is currently under development for the
alignment of the Main Beam quadrupole type 1. The first compact cam mover has passed 1 DOF
tests successfully.
For the Type 1 and Type 4 Main Beam Quadrupoles, the 2nd Generation iron quadrants of the
Type1 were delivered and mechanically measured at CERN Metrology Lab. The complex pole
shapes are well inside a ± 7µm tolerance and this is an extremely good result. The 2nd Generation
Type1 MBQ is now assembled. The procurement of the quadrants for the 2nd Generation Type4
MBQ (~1800 mm length) is still undergoing, due to the difficulties in finding companies
potentially able to provide ultra-precise machining on long components. The imminent magnetic
field quality measurement results should give an indication, on how these tight achieved
tolerances translate into a “beam optics quality” point of view.
Concerning the Intra-train beam stabilisation feedback prototypes for ILC and CLIC: The
upstream coupled loop feedback system was re-commissioned and its impact on the beam near
the IP was measured. For the purpose of obtaining optimal spatial correlation between bunches
in the extracted bunch train the ATF damping ring was set up to extract 2 bunches with a
separation of 274.4 ns. The upstream system was first set up and the optimal gain was selected.
The system was then operated in an interleaved mode with the feedback applied on alternate
machine pulses With the feedback off the second bunch RMS jitter was measured to be
(3.6 ± 0.2) μm in P2, (3.7 ± 0.2) μm in P3 and (3.9 ± 0.2) μm in IPA. With feedback on the
second bunch RMS jitter was measured to be (1.3 ± 0.1) μm in P2, (1.4 ± 0.1) μm in P3 and (2.6 ± 0.1) μm in IPA. The level of correction upstream is as expected given the bunch to bunch
correlations of 94% measured with the same data. At IPA it is clear that the level of jitter
reduction seen in the upstream system does not propagate downstream fully; work is currently
on-going to improve the propagation of the jitter reduction.

Concerning the pulse-to-pulse feedback, different ground motion (GM) models have been used.
Simulations combining different controller strategies show that the GM model has an important
influence on the performance in terms of luminosity or offset. On a variety of reasonable GM
models, the scheme allows reaching an IRMS of the beam motion of about 0.2 nm @ 0.1 Hz
combined with other feedbacks leading to an average luminosity loss of less than 1.7%. Even if
some simplifications have been made concerning the transfer functions and the instrumental
resolutions, the results are well within the required performance to have enough margins when
the detailed accelerator component behaviours are known.

1.1.9.4. Task WP9.4: Beam Delivery System (BDS)
Progress towards objectives
Over the reporting period, the ATF2 laserwire (LW) program was completed with a
measurement of micron scale beams, resulting in uncertainties in the order of 10%; results have
been reported at IPAC2012 and IBIC2012. Outcome of this work is submitted as an article to
Phys. Rev. Special Topics, Accelerators and Beams. Also the ATF2 cavity BPM system could
be completed and is providing essential diagnostics information for ATF2, which recently
demonstrated focused beam sizes of 70 nm. The development work for advanced low-Q CBPMs
was finalized with a test of a low-Q stainless steel prototype, which showed good agreement
with RF simulations. The main developments for the LW during the reporting period were
conducted at PETRA3, where a fibre laser was used to generate laser pulses to collide with the
electron bunches. The development of this system is now complete and first measurements
completed. Two more weeks long measurement campaigns are planned before final publication
of the PETRA3 results.
Cavity Beam Position Monitors
The cavity beam position monitors (CBPM) installed at ATF2 were designed by KEK, built by
Pohang Accelerator Laboratory (South Korea) and are maintained and operated by RHUL in
collaboration with SLAC and KEK. RHUL provided the main readout and control code and
performed the operational support for the system.

Prototype cavity beam position systems (three devices) have proven position resolution at 10s of

Laserwire scanner
Laserwires use a focused beam of laser light that interacts with the charged particle beam only
weakly to provide information on the transverse beam size. This method offers higher resolution
that classical methods, does not disrupt the beam but requires a complex high power laser system
and optical focusing.
A laserwire project was initiated at ATF/ATF2 in 2005 and over the last eight years has
progressed towards the final goal of micrometre scale beam size measurements. Royal Holloway
and the University of Oxford have constructed the entire laserwire system (apart from the laser
which was loaned from KEK). During the reporting period the laserwire has achieved its
technical goal measuring 𝟏 μ𝐦 vertical beam sizes, improving the state of the art from (𝟓 ÷ 𝟏𝟎) 𝛍𝐦 at the start of the project. Figure 48 below gives an example from a detailed
nonlinear vertical scan of an electron beam using 61 laser positions and 20 machine samples,

Prototypes of the beam phase monitor pickup have been completed and tested. Lab RF
measurements are in good agreement with simulations. In Figure 49 the simulation (plots at the
top) and measurement (bottom) results are compared. The plots on the left are the transmission
response between two of the four coaxial outputs, where the resonance of the volume between
the filters is visible. The plots on the right are the transmission between one coaxial output and
one probe placed at one pipe end. The effect of the notch filter is clearly visible. The additional
resonance at ~12.14 GHz in the bottom right plot is introduced by the measurement system and
it is due to a residual probe misalignment that produces excitation of parasitic modes in the
structure.

Within the reporting period the following progress has been achieved:
Two types of beam pick-ups have been characterized with beam. Other than expected the high charge
design worked also best for the low charge regime and will be used for future designs.
The optical front end, which contains the fibre-optical and the opto-mechanical components
necessary to measure the cross-correlation between the laser reference and the electron bunch, was
produced and tested. With the results obtained, a second version was designed with vastly improved
local temperature stabilization to minimize drift effects.
We built a photo receiver and data acquisition using a 12 bit ADC with 500 MS/sec sample rate.
Control and read out were implemented using Matlab scripts.
In extensive beam tests of the full system, the correlation of the drift of the system versus
environmental variables as temperature, humidity and air pressure as well as the machine
parameters as beam charge and size were studied. The obtained time resolution was 20
femtoseconds, corresponding to 0.1° at the CLIC frequency of 12 GHz, which fits well the
required specification.

The main activities concentrate on two different areas: cavity improvements and beam
experiments. Improved methods for cavity treatment such as vertical electro-polishing or sputter
coating are investigated. Prototype work on superconducting (SC) crab-cavities is initiated with
the goal to increase the luminosity of colliders such as LHC, CLIC or ILC. The second research

The fourth SRF Annual Review took place on 25-26 and 29 May 2013 as face-to-face meetings
between the Work Package leader and Task leaders, according to the following agenda:
25 May at DESY, for Tasks 10.8, 10.3, 10.5, 10.7 and 10.6
16 May at CERN, for Tasks 10.1 and 10.4
29 May at CEA, for Task 10.2.
This review was used to finalize the agenda of the missing deliverables and preparation of the
EuCARD Final Meeting on June 6, 2013. Only three Deliverables were still missing on May
29th:
D10.2.1: the cavity RF tests are scheduled in August and September 2013. These tests
are critical milestones for CEA and CNRS in view of their contribution to ESS project.
D10.4.2: the magnetron sputtering facility at INFN-Legnaro is operational and
preliminary tests are promising. No cavity was available for the coating and the RF test.
D10.4.4: due to the transfer of its main author to the ESS AB Company and the fact that
recovering from this situation turned out not to be possible, the only option was to re-
orient the study towards materials and surface aspects in the development of SRF
niobium cavities, including the initial focus of thin film cavities. An interesting outcome
is the write-up of a EuCARD Monograph by C. Antoine (CEA) on this specific topic.

1.1.10.2. Task WP10.2: SC Cavities for proton linac
Progress towards objectives
The first activity of this task has consisted in the fabrication follow-up of the two SPL type
elliptical cavities, manufactured respectively at RI and ZANON companies.
For the β=0.65 cavity, the kick-off meeting took place at RI premises in November 2011. The
manufacturing file was provided to IPN Orsay beginning of March 2012 and the official release
for fabrication was given 2 weeks after. The field flatness tuning process with the bare cavity
was originally planned in October 2012 (and delivery of the complete cavity with its tank in
February 2013) but, because mainly of the overload of the RI and subcontractors workshops, the
fabrication was delayed by more than 5 months. Several intermediate RF measurements of the
half-cells, dumbbells and end-groups have been done between January and February 2013 to
match the target frequency. Final measurement of TM010-π mode after welding and leak tightness
test was 703.265 MHz for expected 703.591 MHz. Because of the fabrication delay for this first
phase, we decided to prepare the cavity (field flatness and heavy BCP preparation) and to send
it back to RI for helium vessel welding before any vertical tests. So, we first BCP etched the
cavity surface of about 200 µm, then, we tune the cavity frequency and accelerating field profile.
The bare cavity was sent back mid of April and the delivery of the complete set (cavity with its
Titanium vessel) is foreseen in June 2013. Next step will be the preparation in clean room and
RF test in vertical cryostat at CEA-Saclay this summer.
For the β=1 cavity, the fabrication contract has started in April 2012. A review of the
manufacturing drawings has been done in July 2012. The forming of the cells by deep drawing
was performed in September 2012. Three sets of intermediate RF measurements on the half cells
and dumbbells have been organized at ZANON factory in presence of CEA. Two steps of RF
trimming were done on the four dumbbells and the two endgroups in order to tune each element
close to the target resonant frequency. After the final equator welding, the measured resonant
frequency of the accelerating mode is 703.747 MHz (703.04 MHz expected). Some upgrades of
the RF measurement tooling have been proposed to ZANON in order to improve the whole
procedure of frequency tuning before final welding. The cavity has been delivered to CEA

without its helium tank in May 2013 for the field flatness tuning. The electropolishing, the clean
room preparation with high pressure rinsing and the test in vertical cryostat is expected before
August 2013.

The second main activity of this work package has consisted in the development of the new
Vertical Electro-Polishing (VEP) set-up. Additional experiments on single-cell cavities have
been carried out with new set of parameters. The use of a low voltage (6V) associated with a
high acid flow rate (25 L/min) has improved the surface finishing of the cavity.
Two single-cell cavities have been tested:
- 1AC3 cavity reached an accelerating gradient of 34 MV/m after 250 µm VEP. The
gradient has been limited by quench, with a heating area located at pits which have appeared
during early treatments with unsuitable parameters.
- 1DE1 cavity reached an accelerating gradient of 42 MV/m after 70 µm VEP. This cavity
has been previously treated on a standard Horizontal Electro Polishing (HEP) system and baked.
This result demonstrates that HEP and VEP configurations offer the same performances for this
cavity in term of gradient and improvement after baking.

electropolished with the parameters previously described (~50µm removal). The observed
surface aspect on 1-cell and 9-cell cavities seemed similar. However, the achieved performance
on the 9-Cell cavity is limited due to heavy field emission. New VEP and RF test sequences are
planned to totally remove field emission.

1.1.10.3. Task WP10.3: LHC & CLIC Crab Cavities (CC)
Progress towards objectives
The LHC-CC prototype fabrication at Niowave Inc. (not foreseen in the EuCARD contract) has
been completed and the cavity has been provisionally processed at CERN (see Figure 54 a) and
a first vertical test performed. The testing at SM18 was restricted due to a vacuum leak, however
the low field performance achieved was encouraging with respect to further testing to be
undertaken (see Figure 54 b). An optimised coaxial input power coupler has been developed
which is identical to the existing LHC accelerating mode cavities (see Figure 54 c) and a loop
type coupler has been developed for damping the LOM and HOM impedances (see Figure 54 d)
with integrated optimisation performed to achieve the required mode damping performance
required (see Figure 54 e).

Two CLIC-CC prototypes have been manufactured for high gradient testing, one by UK
industry (see Figure 55 a) and the other by CERN (see Figure 55 b) using the same manufacturer
as the main CLIC linac cavities. A conventional dual-feed input coupler has been developed to
transversely symmetrise the deflecting field (see Figure 55 c), with waveguide couplers proposed
to control the lower, same and higher order modes (LOM, SOM, HOM), with the most
threatening SOM requiring a damping to the order of Q ~ 100 (see Figure 55 d).

For the CLIC-CC timing and synchronisation system, beam pick-up monitors and a suitable
LLRF board have been developed, using standard analogue controllers which already exist at the
CERN high power test stand, to achieve the required CLIC klystron to beam synchronisation
requirement of 5 fs. A control system model has also been developed to assess the performance
requirements for the LHC-CC system in the presence of beam. Beam protection issues
associated with a cavity quench and other failure mechanisms have been investigated and a
performance assessment of the LHC-CC in a de-tuned state compared to its normal RF operating
mode has been performed.

1.1.10.4. Task WP10.4: Thin films
Progress towards objectives
The different tasks have made good progress. The development of the magnetron sputtering
technique at Legnaro has reached maturity. The RRR of the Nb sputtered samples was increasing
when increasing the power of sputtering. RRR values as high as 22 were obtained. In addition
the Nb film is uniform all over within the cavity. The deposition rate is also very promising: 1
micron in about 15 minutes is more than 10 times faster than the biased diode technique.
Legnaro is now fully ready to test this technique on a real cavity. However, due to the delays in
the production no cavity could be delivered to Legnaro yet. It is expected that the test could occur
after the summer.
The work in Lancaster was discontinued due to the departure of the person in charge. However
the topics have been addressed by Claire Antoine (CEA) in Chapter 5 of her EuCARD report
“Materials and Surface Aspects in the Development of SRF Niobium Cavities” (Vol. XII of
Editorial Series on Accelerator Science), which constitutes the groundwork for the new Thin
Films task of EuCARD2 which will address Hc1 improvements, ALD multilayers and Nb3Sn
thin film production, as well as new thin films test facilities (3rd harmonic Hc1 measurement).
Contractual milestones and deliverables
M10.4.3 QWR sputtering with Nb using the magnetron technique: deposition parameters
have been validated with a stainless steel cathode. Due to the delays in the production no cavity
could be delivered to Legnaro yet but a novel sputtering set-up was thoroughly tested, leading to
a possible patent application.

1.1.10.5. Task WP10.5: HOM distribution
Progress towards objectives
During the 3rd period, we have achieved our final goal within EuCARD of proving that HOM-
based Beam Position Monitors (HOMBPM) can be built for the 3.9 GHz accelerating module
(ACC39) in FLASH.
Sub-task WP10.5.1
Further analysis of the data collected with test electronics in Period 2 and defining the
specifications for the HOMBPM-electronics has been achieved. Although not the same
resolution can be achieved as for the HOMBPMs previously installed at 1.3 GHz in FLASH, we
have shown that the performance achieved with the test electronics, and therefore the one
expected to be achieved with the final one, will be an essential tool in aligning the beam on the
cavity axis, and reducing the beam-excited wakefields. Figure 57 shows the power integrated
around 5.44 GHz measured from each of the 8 HOM couplers as a function of the horizontal and
vertical magnetic steerer current, which is proportional to the beam position. Although each
distribution is different, due to the different ways that the various modes couple to each coupler,
they show a common minimum, which is the aim of the beam alignment procedure. The power
distribution has been studied also with trapped modes in the 5th dipole band. Herewith the
milestone 10.5.1 has been fulfilled.
Figure 57: HOM power around 5.44 GHz for each of the 8 HOM couplers
Based on these results, we decided to build two versions for the HOMBPM-electronics for
FLASH: one based on propagating modes around 5.44 GHz for precise beam position
measurements, and one using trapped modes around 9.06 GHz for localized measurements, both
with a bandwidth of 100 MHz. Two modules of the first type and six of the later will be built at
Fermilab. We expect to get similar or better performance as with the test electronics developed
within the EuCARD project.

They deal with the simulation of radio-frequency properties of ACC39. After creating and
validating computer models in the previous periods, one focus of the 3rd period was the
construction of model order reduction techniques, which are capable to determine secondary
quantities for multi-cavity structures apart from scattering parameters (external quality factors
or transient system responses). Proofs of principles for these methods have been presented
already for simple superconducting radio frequency structures (see literature). Beside of this
theoretical work, the influence of geometrical variations of individual cells in a nine-cell
resonator on the transmission spectra is investigated. The question whether the location of a
perturbed cell in the resonator is simply determinable by looking at the S-parameters was of
special interest. However, this turned out to be very difficult (inverse field problem) and needs
further investigations. Another focus was the dependency of the transmission spectra on input
coupler reflections (refer to Figure 58). Here it turned out that especially the second dipole
passband is very sensitive with respect to input coupler reflections.

1.1.10.6. Task WP10.6: LLRF at FLASH
Progress towards objectives
After getting first results from system operation some system components were modified and
upgraded.
Multichannel Downconverter
The module performs the role of a field detector in the LLRF system. It has been optimized for
an input frequency of 1.3 GHz, a heterodyne of 1.354 GHz and an intermediate frequency of 54
MHz. High performance (low noise, good linearity, low crosstalk) has been verified in 2102 by
measurements of the final revision of the board (Figure 59).
Improved Vector Modulator
The vector modulator board performs the role of an actuator in an LLRF control system. The
RTM form factor provides enough space for two channels. The second channel will be used in
the future to perform system calibration. After extensive tests and requests for new features a
second revision of the board has been developed in 2012 (Figure 60shows a render).
Figure 59 Final revision of the
downconverter module.

modulator module.
Figure 61: RF backplane

Synthesis and distribution of clock and reference signals in xTCA system
The RF backplane has been developed for the MTCA crate used in the LLRF system in order to
increase reliability and maintainability and to reduce the limitations arising from RF cabling. It
distributes high quality LO (local oscillator) and reference signals as well as low-jitter clock
signals. Low-noise analogue power supply is provided to analogue RTM modules. Final revision
of the board is still under tests. The final board installed in the MTCA crate is shown in Figure
61. In June 2012 the patent application for RF backplane was filled in.
Development of an AMC module with fast radiation sensors
It should be mentioned that on 9.01.2013 the patent was granted for “Solid State Neutron
Detection System” (EP 1 729 149 B1). The EuCARD predecessor CARE project supported this
work. It was a base for current development of the radiation monitoring board. During the
reporting period the AMC module for radiation monitoring has been redesigned to fit into
daughterboard of the FMC module.

1.1.10.7. Task WP10.7 SCRF gun at ELBE
Progress towards objectives
Sub-task WP10.7.1: Slice emittance measurements of the SRF gun
This subtask was successfully finished within time. The final report was delivered in month 26.
The work was presented on the DIPAC´11 workshop and the EuCARD 2nd Annual Meeting.
The PhD student, Jeniffa Rudolph, who was responsible for the scientific part in this subtask
defended her thesis “Instruments and techniques for analysing the time-resolved transverse phase
space distribution of high-brightness electron beams” with great success in 2012.
Sub-task WP10.7.2: GaAs photo cathode
The work for the development of an advanced preparation system was continued. In the previous
part of the project (1) the existing system for CsTe cathodes was extended, and later (2) a new
small separate preparation system was build. In both systems the preparation of GaAs
photocathodes was tested, but without success. In the first system, the contamination and the
space for the installation of the components cause major problems. In the second chamber, the
unsatisfied vacuum was the main problem. Activation of GaAs wafers could be performed, but
the quantum efficiency was low and the lifetime was extremely short. The design of the small
preparation chamber and the results of the measurement tests are presented in the final report
D10.7.2. The conclusion of the project results is, to develop a more advance system which
includes the experience of the previous work and state-of-the-art technique in this field:
split of the cathode body and the new plug,
only the plugs are treated in the preparation system,
design of preparation system which can be installed near the electron gun,
using different chambers for cleaning, transfer and preparation.
Furthermore a standard design of the photocathodes, plugs and storage chambers was fixed
between the German institutes HZB, HZDR and University of Mainz. This required a further
redesign but will allow the exchange of photocathodes for tests and characterization between
these institutes in the future. HZDR gives additional funds for investment for this project of 200
k€ in 2012 and 2013. CAD design pictures are shown in Figure 67.

Sub-task WP10.7.3: Evaluation of critical Issues of SRF guns
A substantial progress was the delivery of the new two-channel UV driver laser for the gun in
2012. The work in this subtask was aimed to the following topics:
• Bunch compression studies and measurement of the longitudinal phase space applying the
phase scan technique.
• Operation of the gun with high average current and photocathode lifetime studies. With new
driver laser the average current could be increased up to 350 µA. The latest result is the
extraction of >300 C from a Cs2Te photocathode at a typical current of 300 µA.
• The dark current investigations were continued with comparative study for a series of different
photocathodes, and energy spectra were determined.
• A remarkable progress was the first FEL operation with the SRF gun at ELBE in April 2013.

During the last period, surface treatment tests by plasma discharge were performed on coupler
cold part surfaces. The efficiency of the discharge in surface carbon removal was approved.
However, due to the presence 10% of oxygen in the gas discharge, an increase of oxides in
coupler surface was also observed which leads to the deterioration of coupler performances
(decrease of the RRR parameter). An optimization of gas discharge composition is needed to
avoid such effect. The changes in surface composition cause an increase of its roughness. This
effect is benefic for the RF conditioning process as it causes the lowering of surface secondary
electron emission yield (SEY). This observation must be confirmed by SEY of copper samples
before and after plasma treatment. In addition to an RF conditioning of the coupler part once the
process is fully optimized.
Subtask 10.8.2: Automatic couplers cleaning
After a first study phase providing the machine basic functions and all the components needed
for the cleaning process, a second extensive one was performed to choose the appropriate
technique among available solutions for the different functional steps. Thus, the machine design
evoluate continuously along the study advancement and the fixed choices.
Figure 68: Coupler cleaning machine evolution
Today, the internal and external mechanical structure ensuring functional motions of the system
are defined and its cost is estimated. The same is true for the ultrasonic system representing the
cleaning element. The specifications on hydraulic and air retreatment network are now well
defined, the drawings are ready and the cost is estimated. Further studies are on-going to optimise
the best technical solution for these two items.
Generally speaking, the studies are complete enough to give us a complete overview and
estimation of the feasibility, the process and the cost: the efficiency of the process, as far as the
large mass production is concerned, is undisputed. All the technical functions can be respected
to clean couplers automatically and correctly, without any damage for them.

The main purpose of Task 11.2 was to prove the compatibility of large magnetic detectors with
a new collision scheme based on large Piwinski angle, low–β and Crab-Waist compensation of
the synchro-betatron resonances. Subtask 11.2.1 aimed to apply this collision scheme to the new
DAΦNE Interaction Region (IR) for the upgraded KLOE-2 detector running same time Subtask

luminosity for the data-taking for the KLOE-2 experiment. Figure 69 shows a sketch of the final KLOE2
Interaction region.

Several hardware upgrades have been done in order to improve the collider performances. Among these,
the installation of “clearing electrodes” in the dipole and wiggler vacuum chambers of the positron ring,
to have an almost complete neutralization of the emitted photo-electrons in the e-cloud instability
formation. The experimental measurements on the electrodes effectiveness in mitigating the electron-
cloud effects have proved that they work in increasing the threshold current at which the instability occurs,
so allowing for a higher injected positron current. In Figure 70 the horizontal instability growth rate as
a function of the electrode voltage, as measured using the bunch-by-bunch feedback, is shown.

A massive campaign for further hardware upgrades has been conducted during the 2013 shut-down
(required to install the new layers of the KLOE-2 detector), both in the rings and in the injection complex.
This work will continue after the end of the EuCARD project.
Sub-task WP11.2.2 study of a high luminosity Interaction Region for LHC
The work for Subtask 11.2.2 was delayed due to the problem in recruiting manpower at CERN. This
problem was solved and a doctoral student position was awarded starting from November 2010. For these
reasons the Deliverable 11.2.2 (Study of an IR design for LHC upgrade, CERN) was postponed to M48.
An elegant conceptual optics solution for a future LHC luminosity upgrade, combining flat beams, local
chromatic correction, large Piwinski angle and the option of crab-waist collisions. The scheme requires a
non-zero slope of dispersion at the IP and a new single-aperture final focusing element, which combines
dipole and sextupolar field components. The quadrupole feed down field focuses both beams in the
vertical plane. The sextupole component together with the non-zero dispersion is used to correct the
chromaticity locally. Orbit, dispersion and beta functions were matched to the existing LHC arcs.
Dynamic aperture is still a concern. The geometric aberrations could be corrected perfectly by a second
sextupole if the magnets were short. However the double half quadrupole is quite long, which introduces
intrinsic octupolar aberrations in addition to rendering difficult the compensation with a second sextupole.
A segmentation of the final quadrupole, to confine the sextupole field to a shorter region, is proposed as
mitigation. A similar final focus system, for a single beam was designed and qualified for the LHeC.
Possible merits of, and parameters for, applying the described approach at the HE-LHC have also been
investigated. Successful beam experiments testing key concepts, like crab-waist, large Piwinski angle and
flat beams, were conducted, analysed and prepared at DAΦNE and at the LHC, respectively.

In P3, the following experiments have taken place. For the acceleration of muons, the acceptance
of the accelerator and the dependence of the time of flight of a particle around the accelerator on
the distance from the ideal orbit have both been measured. The latter is as expected. The
measured acceptance is ~1 π mm mrad. Further studies of the COD have been made and an
additional source of perturbation in the horizontal plane identified: the stray field from the
injection septum. In the longer term, it can be fixed by replacing this device, but in short term
corrections have been found which reduce the COD both horizontally and vertically.
More general studies have also been undertaken. These include a successful experiment to
demonstrate the principle of phase rotation planned for the PRISM project. Work is also on-
going to study the effect of tune crossings. In particular, it has already been shown that these
crossings have no impact when the beam is accelerated at the fast rate required for muon
acceleration. The question remains how slow the acceleration can be before these crossings
become a problem. This is important for the use of this type of accelerator for the acceleration
of non-relativistic particles, especially protons, for a variety of medical and other applications.

Task WP11.4 aims to study new instrumentation to diagnose parameters, such as emittance or
relative energy spread, of electron beams produced by laser plasma accelerator. An experimental
methodology is needed because of the present produced low shot to shot reproducibility. The
study will take different approaches for measuring the emittance of these electron beam delivered
by laser plasmas accelerators.
Progress towards objectives
The work foreseen for this EuCARD Task was successfully completed in April 2011 (P2).
Studies have continued on the source and influence of the electron angular momentum. This
came as a surprise because injection models predict that electrons should be injected in the
accelerator with a zero angular momentum. The growth of the angular momentum was explained
by the fact that the laser pulse creates an asymmetric plasma cavity (because it is itself
asymmetric). Electrons which are accelerated in this cavity oscillate with different frequencies
along the two transverse directions, inducing an evolution of the electrons' angular momentum
during the acceleration. This explanation for the origin of the angular momentum is supported
by experimental results and simulations, which agree very well. For example, Figure 71 shows

that for a cavity ellipticity of 20%, a very good agreement between simulations and experiments
is obtained. Thanks to this result, the simulations could be used to estimate the emittance using
both the spatial and spectral measurements. Doing so an emittance of 1 π.mm.mrad was found,
consistent with previous estimates and particle-in-cell simulations. This result comforts the
Deliverable of WP11.4.

2.3 PROJECT MANAGEMENT DURING THE PERIOD
In this last project period, the focus of the management has been to simultaneously maximize the
S/T activities outcome, mitigate the exceptional documentation effort requested from all
researchers and coordinators while maintaining a collaborative spirit by organizing a smooth
transition to EuCARD2 and creating a final brainstorming event around the medium term future
of accelerators for research and applications.
1.1.1. Consortium management tasks and achievements
EuCARD has continued benefitting from stable environment and priorities. Even though the
collection of report of activities and of deliverables remains somewhat challenging, the
significant experience accumulated by the management bodies, Governing Board, Steering
Committee and Project Coordinator on one hand, and the standardized project management
instruments on the other hand, now well-known from all participants, have allowed a smooth
P3 exercise.
The P2 periodic report was delivered with a minor delay. One of the report requirements, given
the large scope and number of tasks of the project, is to efficiently summarize the project
activities using a standardized reporting format experimented in P1 and for interim reports. Each
project task, in most cases involving the collaborations of several partners, is allocated a single
page for scientific progress and achievements, ½ page for management information (schedule,
use of resources) plus space for pictures. This compactness requires a special effort from
researchers, task, work package and project coordinators in selecting the essentials for
presentation, in a way respecting the efforts from 38 partners.
Special care was allocated to the concluding EuCARD meeting, with the goal of maintaining the
spirit of collaboration and hand it over to EuCARD2 or other ventures: The first meeting day
was dedicated to the report of EuCARD achievements from a managerial point of view, with a
final assessment by the Governing Board. The next two days were organized as a workshop with
the ambitious theme of ‘visions for the future of accelerators” for the next 50 years. The invited
speakers were for many world experts, with a significant EuCARD participation, and the
response to this challenge was excellent, as well as the attendance of all parts of this
concluding/workshop/kick-off meeting. The scientific organization of this workshop was a
collaboration of the EuCARD and EuCARD2 project coordinators, and of the coordinator of the
very successful EuCARD WP4 “Accelerator networks”. One of its sessions was covered by the
CERN communication team, with an article in the CERN Courier. The technical organization
was carefully prepared by the project assistant, with help and sponsoring from CERN. Always
in the spirit of consolidating collaborations, the project assistant organized the NBI2012
workshop in support of WP3. She equally gave support to the ESGARD committee meetings,
the meetings at CERN of FP7 ICAN and the activity of FP7 CESSAMag.
EuCARD being extended by 4 months with conditions, the Administrative Manager gave support
to many partners in the interpretation of the conditions.
An important dimension of the management activity and results for EuCARD is the external
relations, both to keep EuCARD in line with the trends in the field and to contribute to sustained
collaborations in the community. This is reported in sections 2.3.7 and 2.3.8.

1.1.2. Budget adjustments
No budget adjustments needed to be carried out during the reference period. The final
distribution of the EC funding to each beneficiary will be decided by the Governing Board after
the submission of the final report, taking into account the estimated full costs incurred by each
partner with respect to the commitments in Annex I.
1.1.3. Problems and solutions
During Period 3, the project has not faced significant problems that could not be essentially
resolved at the task’s level.
1.1.4. Changes in the consortium and/or legal status of beneficiaries
No changes were recorded in this last EuCARD period.

1.1.6. Project status
At the end of the project, almost all milestones have been met, not more than 10% had had to be
rescheduled due to delays, some were fulfilled ahead of schedule and a minor number were either
cancelled for lack of relevance, or combined with their respective deliverables. Milestones have
played an important role in monitoring the progress towards deliverables, as most deliverables
are by essence scheduled at the project end.
Out of 63 contractual deliverables,
59 are delivered as planned.

one is delivered by another partner of the collaboration, after the resignation of a key
person at the lead partner. This deliverable is as well published in the EuCARD
monograph series.
three important deliverables will be fully documented during the project but will reach
full completion after the project end: one with about a one month delay (super-
conducting proton cavities), another with a five month delay (HTS insert) and the third
one with a delay estimated at 1.5 years. In the first case, the delay is explained by a
delayed order, following an unexpected cost increase, requiring the mobilization of
unplanned partner funds. In the second case, initial technical difficulties in this risky
R&D line are at the origin of the few month delay. All components have been
delivered, but the assembly and test will be carried out in the last part of 2013. In the
last case (High Field magnet model), 50% of the delay is due to the case of force
majeure after the LHC incident, where all magnet engineers were mobilized for the
repairs during one year. The other 50% are explained by additional iterations that
became required, given this new and very challenging technology, in agreement with
the recommendations of an international expert committee. The progress made by the
European team is judged excellent by the US experts, where much larger funds have
been dedicated to the topic over two the last two decades.
The two EuCARD Transnational-Access facilities have fully fulfilled their objectives and
beyond. WP5 had suffered a delay of 2 years due to the LHC incident; its very efficient recovery
has allowed fulfilling the contract. WP6 almost doubles its contractual commitment, by a strict
control of expenses and the donation of the TA management time by STFC.

Finally the networks, beyond their contractual commitments, have systematically shown
significant added value and visible impact, confirming the strategy of increasing their share and
scope in EuCARD2.

extension of the EuCARD Newsletter to three other FP7 accelerator projects, as a first phase
towards extending it to the whole accelerator community has been effective over this period. The
experience is positive and this new electronic publication is taken over by TIARA-PP with the
termination of EuCARD.
1.1.8. Coordination of activities between beneficiaries and synergies with other projects
An essential ingredient of success for EuCARD as a collaborative venture is to remain integrated
in the accelerator R&D programmes carried out on a national or laboratory basis, which provide
2/3 of the project funding. In this respect, the selection of EuCARD tasks and coordinators has
been instrumental. The coordination between beneficiaries is efficiently done at the task level,
with the EuCARD activities embedded in local projects, and providing the added value of a
collaborative venture. One indication is the number of conference publications, signed by authors
within and outside EuCARD.
To further strengthen the links between EuCARD beneficiaries, the face-to-face Steering
Committee meetings and the Annual meetings have been held in different laboratories. On each
of these events, either half a day (for SC meetings) or a full day (for annual meetings) is dedicated
to the host laboratory/state and beyond, including political and scientific talks and discussions,
and visits of accelerator infrastructures. In P3, the steering committee meeting organized in
Uppsala University was only partly faced to face, a snowstorm preventing landing in Stockholm;
the Annual meeting of 2012 took place in Warsaw, hosted by Politechnila Warszawska, , and the
Concluding meeting of 2013 at CERN, as coordinator. Once again, the “host day” in Poland was
a very valuable opportunity to demonstrate the R&D potential of Polish Institutes. ESGARD
organized as well a satellite meeting during these two EuCARD annual meetings.
The network events (mainly topical workshops) are privileged opportunities to create links
between the EuCARD beneficiaries and beyond, especially the US and Japanese partners, who
have been active participants. The WP3 network on neutrino facilities published important
synthesis documents proposing perspective for this branch of physics, used as input in the update
of the European policy for HEP. After setting up collaborations on superconducting crab cavities,
LHC luminosity and energy upgrade and novel acceleration techniques in the former periods,
the WP4 accelerator network has continued to be the birth place or catalyser of collaborative
“start-ups” active on major new perspectives for frontier accelerators, such as TLEP and
VHELHC, gamma colliders,…
The coordinators of EuCARD and EuCARD2 are tightly collaborating, for an optimal
transmission of experience. This is further consolidated by a common coordination office.
Whether on behalf of CERN or ESGARD, in the latter case together with its chairman R.
Aleksan, the coordinator has visited the EC or participated, with the Administrative Manager, to
the CERN delegations hosting visitors from the EC, keeping contact and explaining the
motivations for the R&D in accelerators. The project coordinator represents CERN and
EuCARD in the FP7 ICAN project, creating a link between the laser and accelerator
communities. He coordinates as well the FP7 CESSAMag project, whereby the European
Commission and CERN organize a support to SESAME, in the framework of Euro-
Mediterranean scientific cooperation.
The EuCARD administrative manager, in is duty of head of the CERN EU Office, frequently
visits the EC, keeping an efficient link that profits all EuCARD partners.
