Due to Due to late availabilitylate availability of services of services level-by-levellevel-by-level strategy adopted strategy adopted in the pitin 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:Level III: check full functionality and sign-off of complete sectors – done only when final services available final services available MDT+RPC/LVL1MDT+RPC/LVL1:

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)

Phase II commissioning: Integration in Phase II commissioning: Integration in ATLASATLAS

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

ConclusionsConclusionsConclusionsConclusions

Installation almost completedleft over only due to interference with other

detectors or unavailability of BOG chambers Services Installation:

Cabling almost finished moving to rack dressing DCS, Alignment and DAQ systems well under way. Level III Sector commissioning starting now

Very tight schedule and shortage of final power supply.

Sectors will be available for integration in ATLAS Toroid test with cosmic rays showed good results
