All CMS 30 May07 TSV1 All CMS 3 30 May 2007 LHC machine CMS Progress Overall Schedule

All CMS 30 May07 TSV2 News on the Machine Update on Triplets From CERN Homepage and Fermilab Today. Proposed to add to each Q1 magnet and each Q3 magnet a set of four cartridges that can absorb the longitudinal force generated during the pressure test. The solution was presented to a team of experts during a review at CERN on April 24 and 25. Since then the design of the cartridge system has been refined and parts needed for the cartridges and their installation have been ordered. The installation of the cartridges in the Q1 and Q3 magnet of at least one inner triplet is scheduled to be complete in early June, in time for the next pressure test. DG, DDG and LHC Project Leader to meet soon. Most likely will be given information soon afterwards.

All CMS 30 May07 TSV3 CMS progress UX: 2 DT sectors in YB0 commissioned with cosmics. All 18 EB- SMs inserted, YB0 services installation ongoing (showing ~ 3 week delay). Started installing tracker radial cable trays this week and start cabling of S1 towards the end of this week/beginning next week. HF+ commissioned. Conducting a global run now SX: YB-1 commissioned using cosmics (almost done), RE-2 chambers mounted - testing and commissioning. Cabling of YB-2 will finish soon. RPC HV cabling end-June. Tracker: Cosmics data being taken. Started process of going cold last week. Taking cosmics at 10C. ECAL: EB- installed, 25 SMs integrated (electronics). 20 supercrystals mounted on ‘Dee4’. Over EE 2500 crystals delivered. Finalize schedule for final order (this week).

All CMS 30 May07 TSV12 Points for Discussion Discuss new optimized CMS schedule during MB of 11 June - also use for AR, CMS Week and CR (involve wide constituency) Annual Reviews: June, agenda sent out this morning. CMS Week: June, Plenary sessions in 2 parts. Under construction. SLHC: need to prepare the next steps. Formulate a proposal by June MB ? RPC_RE Workshop: 25, 26 June at CERN - invite all interested parties. SLIMOS shifts - several incidents point to the need to start such shifts - will now actively canvas for volunteers (must not be solely people usually busy at Point 5 or on other critical path activities) Publications Conference Committee Constitution MoA’s
