10. 10 Commissioning Strategy All stations arrived at ATLAS after cosmic ray certification and retested at SX1 (now dismissed) Due to late availability of services level-by-level strategy adopted in the pit Level I: Level I: fast test of station integrity: gas tightness, broken wires Level II: Level II: check basic functionalities with provisional services: DCS, FE elx. behavior, in some cases also noise runs Level III: final services available  MDT+RPC/LVL1 Level III: check full functionality and sign-off of complete sectors – done only when final services available  MDT+RPC/LVL1: Full test up to cosmic ray run First determination of optimal working point Dead channels maps, … After Level III Full SECTORS ready to be integrated in ATLAS: commissioning Phase II

11. 11 MDT test up to Level II MDT: 216/630 tested Mainly Inner chamber difficult to access later (BIL and BIS) Up to now test done using provisional services Since January moved to final services  sector 5 and 6 DONE with FINAL services Many problems found and fixed: mainly damaged components: ELMB, CSM, cables, fibers,…

12. 12 LVL III -Full Sectors commissioning schedule Constraints Possibility/Access to position stations Availability of services + CAEN Power supplies Strategy: start from top sectors Schedule Sector 5 and 6: April/May (Under way) Sectors: 3–4 7-8 1-2 9-10 13-14-12 11-15-16 Month: June July Aug Sept Oct. Nov. PS schedule: October ‘07 ~80% of RPC/LVL1 and only 40% of MDT LV expected: After sector 5/6 move around “Jolly” set of CAEN boards to commission all other sectors (depending on delivery from CAEN) Only part of the barrel integrated in ATLAS by fall 2007

13. 13 Phase II commissioning: Integration in ATLAS Integration of sector 13 in March combined ATLAS run: MDT: ROD-ROS readout – HV/LV DCS integrated RPC/LVL1: VME readout – muon trigger via MUTCPI-CTP Starting from June integrate sector 5A & 6A (after we have commissioned it):  Use these sectors as benchmark for phase II to include all final features needed in ATLAS: DCS, DSS, chamber initialization, configuration DB, high level muon trigger, Data analisys 1 FULL CAEN PS set left on this sector Other sectors can be added later once are signed off depending on PS availability
