Alignment of close supports on back A and C sides completed  ready to install chambers here also M1C central part cable rearrangement completed – back sides missing Chamber testing has started – see Fernando presentation Measured the position of the top alignment bars HV cables connected to CAEN PS and tested successfully A side closed Friday afternoon for two weeks for CALO works Continued timing test on M2-M5, 23 more channels recovered, 250 to go (1.5% of the total)

2. 02-Mar-09A. Cardini / CERN & INFN2 Muon Detector Plans (week 10: Mar 2 nd  Mar 6 th ) Present: Burkhard, Ale, Thomas, Nikolai, Oleg, Sasha, Francesco, Fernando, Maria Luisa, Landi, Santoni, Stas, Messi Continue installing R4 (+ some R3) chambers on C front (today) and back (from tomorrow) Proposal to postpone the removal of the top of the structure on C-side beginning next week: –Recover ½ day delay accumulated last week caused by lift problems –Optimal use of manpower this week Continue test on A and C sides –Debug problematic chambers –Start connectivity test –Start connecting chambers to gas system, now in open mode for this reason M1 CAEN HV testing (with cables) on C side GEM gas system leak test at 5 mbar Continue M2-M5 timing tests
