28/4/2004 16th RRB J. Schukraft 4 Funding Issues US participation ~ 10 M$: EMCAL for jet physics NSAC sub committee on US heavy ion program (GSI/RHIC/LHC) final report October 2004 with positive recommendation for LHC proposals exist from ALICE, Atlas and CMS Japan & China Japanese participation (~ 10 M$): TRD, PHOS proposal not funded in 2004, may be resubmitted end 2004 Chinese participation (~ 3 MSF): PHOS proposal now to be submitted to MoST & MoE (no longer NSFC) Consequences for PHOS with the resources available we will be able to built only 3 modules 1 ready for installation in 2006/2007/2008 each.. The LHC will open up a new regime in relativistic heavy-ion physics with significant opportunities for new discoveries. The Subcommittee recommends that: Participation at the LHC should become a new component of the U.S. Heavy-Ion program. This participation should receive comparable investment priority with each of the near-term upgrade programs for the two large RHIC detectors.

28/4/2004 16th RRB J. Schukraft 5 Funding Issues M&O contributions Poland has not signed the M&O MoU, outstanding bill ~ 72 kCHF signing the M&O MoU seems however to be under consideration CORE construction funds The Polish Institutes have been informed that only 50% of the requested CORE funds will be available starting this year (2004): Total CORE contribution: 450 k (PHOS), 450 k (TPC), 100 k (CF) delivered 1997 – 2003:180 k150 k 82 k request 2004: 90 k 90 k 18 k request 2005: 50 k153 k 15 k Situation seems to be similar in the other LHC experiments Situation to be discussed between LHC expts, CERN Management & Funding Agency

28/4/2004 16th RRB J. Schukraft 7 Installation, Large Structures Main installation crane was out of service for 3 months major disruption to installation activities impact minimized using mobile cranes and re-scheduling of activities worry: all cranes show signs of instability (20 years old, now full in use) Space frame load tests and installation tests proceeding dummy TRD and TOF modules inserted successfully (after some error corrections !) first load tests & deformation measurements done pre-commissioning takes longer than foreseen, but is vital to correct errors ! Muon arm foundation finished Muon Magnet: Coils were inserted proved to be much more difficult and time consuming than foreseen installation in final position: delayed to early 2005 (still not on critical path) power test: end October Muon absorber assembly under way one section finished, remaining two in progress

28/4/2004 16th RRB J. Schukraft 29 Milestones Situation remains very tight: Not loosing further ground, but not (yet) catching up delays not (yet) critical: Muon magnet & chambers, large structures critical path items: ITS in general, SPD in particular; TRD actions to recuperate delays have been identified revised schedule to be discussed with LHCC in March (CR5) to be coordinated with machine progress (news expected early 2005) LHCC Milestones September 2004

28/4/2004 16th RRB J. Schukraft 30 Summary Collaboration major decisions outstanding (US, Japan, China) Funding major uncertainty : PHOS, TRD: awaiting decisions in China & Japan not funded: 40% of TRD, 2 PHOS modules, EmCal (new, USA) Detector construction major problems solved: SPD: bump bonding now with good yield on larger series TOF: HPTDC yield in 2 nd production ok core software manpower: secured additional help for next ~ 2-3 years major problems remaining: SPD: sensor wafer delamination, MCM supply, VERY TIGHT SCHEDULE for ITS TRD: delay in FEE (redesign of masks and board) core software manpower: stability of CORE staff at CERN: discussions ongoing
