News:CLIC workshop very successful.
• Next years workshop end February/early March,
partly combining with general LC discussion (ahead
of open ESU meeting in May 2019)
CLEAR and X-boxes doing well – see reports
• CLEAR review late this year, early next year
A 3.5 GeV CLIC type linac (klystron driven) being
discussed in framework of the Physics Beyond Colliders
– see report later
Work in implementation groups (CEIS, Cost & Power,
Main Linac Hardware, Parameters, Novel Acc.) moving
ahead well – you will see some flavours of it today
PiP writing – we will see today where we are
Physics and Detector work progressing well, external
review this week

MTP budgeting 2018-19 not changed, first discussion
of 2020+, see following slides

Key goals (c/p/indu/risk)
3
Modules (drive-beam,
klystron type)
Final modules, from revised
designs to industrial modules
Optimized structure
and RF components
Finalize industrial structures:
increase manufacturability,
brazed, halves, conditioning.
Use/maintain/operate existing
test-stands for testing
Klystrons and
Modulators
Efficiency and costs
improvements, significant
gains possible for efficiency,
industrial cost-models and
optimization
Magnets
Permanent magnets, longit.
variable magnets, industrial
production and cost-
optimisation
Civil engineering,
infrastructure
Detailed site layout and
CE/infrastructure designs

CERNenergyconsumption2012:1.35TWh
18 April 2018 Budget planning
A cost of ~6 BCHF and power ~200 MW are “reasonable” values
Focus TDR work on modules, RF and CE for costs; for power RF and magnets
Above: EU Design Study for X-Band FELs
2018-2020: http://compact-light.web.cern.ch
Beyond being a collaboration for CLIC, many
groups have their own X-band facilities and
components (see overview on the left)

In the CLIC preparation phase:
Take advantage of the widespread use of electron linacs, and rapidly increasing use
of X-band increase collaboration
An e-beam facility at CERN
ILC prep. phase project:
CERN coordination of European effort
R&D contracts
MoU annexes or similar (with MS and NMS collaborators)
Techn.Transfer agreements, EU projects.
Preparation Phase 2019-22: Organization and resources
A European ILC project in the preparation phase 2019-22: • Resources needed estimated to ~25 MCHF/year (material) and 60 FTE/year (personnel),
ramping up from 2019 • Move towards more engineering personnel • The organisational model above is used for existing studies at CERN, e.g. CLIC/HE-LHC/FCC
Choices and common activities
18 April 2018 Budget planning 9
CLIC prep.phase / year
• 21 MCHF (w/collaboration)
• 130 FTE (w/collaboration)
ILC prep.phase /year
• 25 MCHF (Euro-collaboration)
• 60 FTE (Euro-collaboration)
3.5 GeV machine
• 6.5 MCHF (CERN)
• 55 FTE (w/collaboration)
For the time being• Look at common areas in all scenarios – consider key topics or facilities 2019-2023
• Cover all existing existing agreements with (INFN, UK, etc) that go into 2020, it also covers CompactLight obligations, ARIES transnational access, LCC:
• By 2019-2020 we need to know where to go next to select between the circles on previous slide to for more solid and concrete planning
• No changes needed for 2018-19
• *in case of ILC ramp down after 2021 (move Xbox facilities partly outside) – other ILC activ. will come in
