AFP 0+2Single Arm, 2 Roman Pot Stations (206 m, 214 m)• Earliest opportunity to install: Winter 2015-16 SSD (9

wks!)–AFP Beam Pipe section ~9 m–RP Stations + BPM–Cables–Vacuum, Cooling

• Tracking detectors–4 planes of 3D Silicon Pixels; edgeless (150 um)–provides L1 Trigger from FE-I4 HitOR outputs (e.g. 3 planes out

of 4)–can be installed during a short (6 hr) access

• NO Time-of-Flight for AFP0+2:–ToF not needed/useful for 1-arm physics …–only for study of time structure of backgrounds install only if the rest is done !

ATLAS USC Mtg 22JAN2015 6

a VERY large job in VERY little time !

AFP TDR (2)

ATLAS USC Mtg 22JAN2015 8

Summary TDR• Draft version ready:

–Some missing sections which are not too important for AFP 0+2

• Final Version in for Collaboration review (after AFP Kick-off)–Required for final version:–Clean-up–Critical read by AFP

ATLAS USC Mtg 22JAN2015 9

AFP0+2 Cost Summary • Need new Collaborators / new Responsibilities:

– Not covered Detector Projects (=?): ~36 KCHF• Si Tracker Card• Si Tracker Holder• (Reference Clock for ToF – for AFP2+2)

– Not Covered Infrastructure (=??): ~155 KCHF• RP Stations (20 KCHF from CZR)

– Motors, Transducers, etc.– Feedthroughs for SiT, ToF, Services

• RPS support tables• Roman Pots (UAE, SBU?)• BPM (1 per arm)• Vacuum Pump• Patch panels & Cables• (TCL6 ?)

• Institutional contributions will be confirmedat the time of the kick-off meeting

Summary Manpower (2015)

The estimate (also using ALFA experience) suggests we need:• Urgent:

– 1 FTE of onsite TC (+ 1 FTE PL + 0.3 FTE RC)– 0.5 FTE of onsite Project/Mechanical Engineer: assistance with oversight of RP

Station assembly, Detector integration, LHC integration, installation. To work closely also with ATLAS TC.

– 1.0 FTE of a good onsite Technician with experience in UHV work and electrical work: RP Station assembly, Detector integration, installation (FD M&O B)

– 0.2 FTE of offsite Mechanical Engineer/Designer for the Silicon Tracker (sensor cards and holder in pot)

• Not Urgent:– 0.2 FTE for 0.3 year of Mechanical Engineer/Designer for the Time-of-Flight  (detector

 holder) 

• Some of the above could be split: it would be very advantageous to have a local mechanical/UHV engineer in Prague to follow the RP Station production and Vortex Cooling at Vakuum Praha and at CTU. This same person might also work on the Si Tracker holder.

• Similar manpower required for 2016: Installation of AFP2+2 in Winter SD 2016/17

In RED the roles still not definitively assigned

Proposal for Next Steps• Letter to the institutes: sent on Jan 22nd with

deadline Feb 2nd (only one answer until now)• PL election: (after IB) Jan 29th- Feb 12th (Probably

better to be postponed after the CB approval)• Kick-off meeting: February 3rd

• If missing resources (see Michael) for 1 arm installation are found, try to target:– EB approval: February 6th

– CB approval: February 20th – LHCC approval: March 4-5th (very tight) or June 3-4th

Deliverables

• Tracking: Installazione 2015/2016 (Resp. IFAE)– DCS, regolatori LV– Flex design (coll. con Oslo?)– Disegno e realizzazione meccanica tracker – Front end chips (ce ne sono 4 e ne servono una decina)

• Completamento 2016/2017– Sensor wafers– Front end chips

• RUN3– Timing con diamanti

Backup

Immediate Actions – RP Stations

• RP Stations–Contacted Vakuum Praha

• RP Station on critical path! Drawings!• identify local contact engineer …

–Start process of Procurement & Engineering Change Requests• Tight collaboration with ATLAS TC

– profit from ALFA and TOTEM experience» Asked Patrick Fassnacht for help

• Order of business:– Cable Trays: procurement, contact with LHC …– Cable installation: define types, procurement, LHC certification …– Station support and footing– Dummy beam pipe installation scenario

–Roman Pot fabrication:• Decide TOTEM Pot or AFP Pot !

AFP-MB Mtg 27JAN2015 16

Note: Station + Infrastructure is most urgent; Detectors can be installed during short access …

When can we start actual procurement for AFP ???

Immediate Actions - Infrastructure

• Infrastructure in the Tunnel–Prepare AFP Pipe section–BPM

• 1 BPM per arm (at 214 m station)

–Vacuum Pump–Cooling

• Vortex Cooling!

–DCS• Elzbieta has started on a detailed scheme • AFP Beam/interlocks: contact with Sigi Wenig

–DAQ• started order for Optoboard(s)

–Cables & Trays• define cable types, numbers, paths from LHC-approved types• patch panel layouts, locations

AFP-MB Mtg 27JAN2015 17

Immediate Actions - Detectors

• Si Tracker–FE-I4 procurement

• on critical path !– get FE-I4 wafers from Bonn

–Design/Engineering/Production:• HDI (`flex’)

– Asked Ole Rohne (Oslo) for a meeting …

• Layer card (?)• Card holder (?)

• Trigger–HitOR Output trigger (LIP ?)

• design trigger (majority) coincidence card (e.g. 3 out of 4 planes)• trigger driver• trigger receiver and CTP interface
