  1. 16th ALICE RRB Collaboration Status Project Status Integration, large structures Detectors (selection) Planning, Milestones CERN-RRB-2004-044 16th ALICE RRB J. Schukraft

  2. 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..

  3. ACCORDE TOF TRD HMPID TPC PMD PHOS ITS Muon arm ALICE Detector

  4. 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 • most pieces at CERN, assembly to start in May

  10. L3 Magnet with Support Beams & Service Wheel

  11. Muon Magnet Yoke • Muon Yoke arrived from JINR between Oct and February • > 8 months delay ! However, assembly went very smooth • Consequences for Installation: Parallel work in the pit required

  12. Yoke Assembly completed 19 Feb 2004

  13. Steel cone from Finland Aluminum from Armenia Lead from England Italian polyethylene Graphite & Steel from India Support from Italy Tungsten from China Muon Absorber Components • complex mechanical piece ~ 100 tons (W, Fe, C, concrete, ..) • Material mostly at CERN, assembly will start in May • after extensive re-design ‘to cost’ now slightly below CORE cost ! • Global collaboration with Institutes & Industry from over the world Concrete from France, Assembly team from Russia,

  14. Silicon Pixel Detector SPD • successful system beam test Oct. ’03 • including full FEE and DAQ • bump bonding at VTT (Finland) • 5 very good assemblies end ’03 & early ’04 (e > 99%) • production schedule agreed with LHCb • production start April ’04 • assembly sites • Padova/Legnaro, Bari operational • Status • viable schedule, but tight & little contingency • yield and speed of mass production to be verified • Action: • reduce number of assemblies by ~ 30% • production & assembly yield now estimated to be better Bump Bonding Yield ~ 300 missing channels out of > 200 000

  15. Silicon Drift Detector SDD • Detectors • NTD raw material now available from 2 (!) suppliers • start of detector mass production April ’04 • FEE • engineering runs ok, sufficient chips available for start of production • production runs start by summer • Status • viable schedule, but tight & little contingency • yield and speed of mass production to be verified • Action: • foresee double shifts for assemblies starting in 2005 Pre-production SDD’s

  16. P-Hybrid Sensor N-Hybrid Silicon Strip Detector SSD • Production: • sensors • 2 producers had production problems (solved now) • Action: additional order to ITC (=> not critical) • FEE electronics: all chips in production • micro-cables & hybrids (Ukraine): • production delayed (funding), now rapid progress • Assembly funding by ministry starting May • sites ready; small series pre-production validated • Strasbourg, Trieste, Helsinki, NIKHEF, Nantes to follow • Status • viable schedule, but very tight & no contingency • mass production of cables & hybrids on critical path • yield and speed of module assembly to be verified • Action: • startup funding for cables & hybrids found • looking for additional production site in Spain(make use of existing infrastructure & interested groups)

  17. TPC Final Gas system • Field Cage • most of delay recuperated • finished : June ‘04 • Chambers finished by May • IROC: 100 % done , OROC: 75 % done • Electronics • wellon track for start of installation • decision in rad. tolerant FPGA to be made • Services: Gas system finished • Planning • system test with beam: May – June 2004 • IROC, full electronics, DAQ, DCS • integration tests (ITS, Space Frame): 8-10 ’04 • ROC installation: start end ’04 • FEE installation: start May ’05 • pre-commissioning (laser, cosmics): June ’05 – Feb. ’06 • final installation: 5 ‘06 Laser system

  21. PHOS • technical progress correct • crystal production (Apatity, Russia): • very smooth, excellent quality • now 5000 (of 18,000) crystals accepted • ~650 crystals from Ukraine (financed by JINR & Poland) • electronics, mechanics, services: • design & prototyping ongoing • but major uncertainties in funding • crystals financed largely from additional resources in Russia (MinAtom, Kurchatov Inst.) • yearly allocation, recent re-structuring of Govt. in Russia ? • no final decision on participation from China & Japan • very good ‘informal’ collaboration & participation in R&D • Consequence: ‘staging’ of PHOS modules • current finances sufficient for 3 (out of 5) modules • installation of one module each in 2006/7/8 Light Yield ALICE & CMS type crystals Apatity, Russia

  22. Trigger Chambers Production of R/O strips, Torino, Italy Muon Arm • Tracking Chambers: mass production started • Station 1 & 2: new design validated in lab & in beam • Station 3/4/5: all 4 production sites started • large gain dispersion in FEE (Manas) => calibration needed • Trigger Chambers: mass production started • chambers, FEE, trigger: all well on track • assembly & integration of full trigger only by mid 2006: somewhat tight Module 0 of Station 2 Kolkata, India

  23. Other Detector Systems • HMPID: well on track • 50% of modules completed, rest by end 2004 • beam test performance above specs; system integration & services very advanced • ZDC: well on track • neutron calo’s finished & tested, proton calo’s under construction • PMD: well on track • re-location addendum to TDR approved by LHCC; construction started • Forward Detectors (V0, T0, FMD): progress, to be accelerated • TDR delayed to September (final design choices to be made) • TRD: on track • chamber mass production started (Heidelberg, JINR) or to start in July (GSI, Bucharest) • electronics in production (PASA) or pre-production (TRAP) • TOF: on track • module 0, services & FEE chain validated, mass production about to start (tenders ongoing) • HPTDC production run: very low yield ! (under investigation) • Trigger, DAQ, HLT, Control (DCS, ECS): TDR submitted Jan 2004 • all systems progressing well and on schedule • major activity of integration of these systems with detectors has started

  29. 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 • additional funding (~ 100 kSF/y) needed; via Cat A M&O ??

  30. October2003: Significant number of delays and missed Milestones Milestones • Action: In depth internal planning and status review of all major projects

  31. January 2004: getting back on track ALICE LHCC Milestones - January 2004 500 450 400 350 nb of milestones 300 Baseline 250 Passed 200 150 100 50 0 Jul-98 Aug-99 Oct-00 Nov-01 Dec-02 Jan-04 Feb-05 Mar-06 Apr-07 Jun-08 Milestones

  32. Installation dates ( unchanged since early 2003, except for Muons and PHOS) C.W.Fabjan

  33. 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 • majorproblems 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 • majorproblems remaining: • ITS: tight schedule, pre-production just started • forward detectors: slow progress in design choices • core software manpower: secure additional contributions & finances
