In 2007 CAEN will deliver:
80% of RPC and barrel LVL1 PS (HV/LV)
80% of TGC
40% of the LV for MDT
25% of the HV for MDT-CSC
MDT Commissioning issues:
HV/LV boards for sectors 5 & 6 Available
Need more boards for the commissioning of other
sectors

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:
Full test up to cosmic ray runFirst determination of optimal working pointDead channels maps, …
After Level III Full SECTORS ready to be integrated After Level III Full SECTORS ready to be integrated in ATLAS: commissioning Phase IIin ATLAS: commissioning Phase 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,…

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

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