Collaboration Status
 Institutes
 new: CTU Prague (Czech Republic)
 participates in ITS and TDR
 contacts: Turkey, Brazil, Spain, Pakistan …
 Organization
 Chris Fabjan re-elected as Technical Coordinator for 3 years
 elections in 2004: CB chair (cur: L. Riccati), Deputy Spokesperson (cur: Y. Schutz)
 Funding Issues
 US participation (~ 10 M$): EMCAL for jet physics
 NSAC sub committee on US heavy ion program (GSI/RHIC/LHC)
 intermediate report by July, final report by September 2004
 Japanese participation (~ 10 M$): TRD, PHOS
 proposal re-submitted end 2003, feedback expected spring 2004
 Chinese participation (~ 3 MSF): PHOS
 new proposal at NSFC, no reaction so far..
 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..

Installation, Services, Large Structures
 Services, electronic racks
 design work to root services, cables etc..
 first services installed at back door of L3
 concern: magnetic stray field at electronics rack locations (50 G – 200 G)
 miniaturization of components since L3-times (eg cooling fans !)
 => more sensitive to stray fields
 implications & remedies under investigation
 Space frame & support frames all finished
 transferred to SXL2 for load tests and integration with TPC & ITS
 additional activity planned for summer 2004
 initiated after discussions during the LHCC installation reviews
 L3 magnet: back door permanently closed in March
 Muon Magnet: Yoke pre-assembly finished
 power test: after summer
 installation in final position: starting October
 Muon absorber

 but major uncertainties in funding
 crystals financed largely from additional resources
in Russia (MinAtom, Kurchatov Inst.)

Offline
 3rd Physics Data challenge (10% capacity): Jan – June 2004
 Goals: Continuous testing of the ALICE computing model:
 Reconstruction (AliROOT), production (AliEn) and analysis (AliROOT+AliEn+PROOF)
 Produce and analyze the 10% equivalent of the yearly ALICE raw data output.
Detailed study of hard physics for the PPR
 Status:
 Currently in the first 1/3 of the program (event production)
 Successfully using combined AliEn and LCG resources (50/50)
 core software manpower: LHCC review 9/2003
a) increase long term staff from < 30% to ~ 50%: discussion with CERN, no progress yet
b) need 3-4 additional FTE: discussion with the major ALICE FA’s
 Italy: willing to send 2 young people (from LCG manpower funds)
 France: long term mission to CERN of one senior person agreed (incl. base salary)
BUT: ‘non residence allowance’ needed from ALICE
 Germany: under discussion (from LCG manpower funds)
BUT: remaining funds for 2004/2005 only ½ FTE
 UK: missed ‘eScience’ call (early-mid ’03)
BUT: exploring other options
 hopefully sufficient ‘volunteers’ for offline

China 10/2003 J. Schukraft
 additional funding (~ 100 kSF/y) needed; via Cat A M&O ??

 Detector construction
 major problems solved:
 TPC: inner field cage delay mostly recuperated
 muon tracking: start of mass production
 muon magnet: all pieces at CERN, pre-assembly finally started
 ITS micro-cables: production quickly ramping up
 major problems remaining:
 ITS: tight schedule, pre-production just started
 forward detectors: slow progress in design choices
 core software manpower: secure additional contributions & finances
