1 Luminosity Monitor MWPCs, commissioning. A.Kiselev OLYMPUS Collaboration Meeting DESY, Hamburg, 27.06.2011

2 Equipment status  First two chambers tested in DORIS test run in February  Two more chambers checked in test beam 22 in May-June  Last two chambers to be delivered to DESY on July,3 …  … and tested in DORIS hall on July,4-5  Survey and final mounting in experiment on July,6-7  Missing CROS3 on-board electronics to be in HH on July,4  see short summary report to this meeting  see extensive report to the April’2011 meeting

3 Equipment status, continued  Gas system will be finished next week  Low voltage: use Rome modules  High voltage: hope to use OLYMPUS spares  Patch panels, cabling, trays, etc: two coming weeks  Electronics hut installation: next week  CROS3 readout: tested in DORIS and test beam 22 runs  Integration in Bonn DAQ: completed in DORIS test run

4 Test installation in OLYMPUS  MWPCs fit comfortable to the support rails  (Almost) no conflict with the drift chambers

5 MWPC design (April’2011 slide) CROS3 readout for the final setup  require design modifications! everything seems to fit together  will check in May with CROS3 have more freedom to vary Z-positions … … but also there are more problems with the cables  fine tuning in progress

6 Test installation in OLYMPUS  Comfortable clearance to the toroid coils  Yet space will become very busy after on-board electronics and cabling installation

7 Summary Test installation in OLYMPUS was successful Most part of equipment is delivered to DESY and checked Remaining part will be in HH in a week from now Full installation will require one more week
