Online (GNAM) and offline (Express Stream and Tier0) monitoring produced results during cosmic/collision runs (Oct-Dec 2009) Shifter and expert level monitoring histograms At low level (raw and prep-raw data), mid level (cluster) and high level (track ) Online monitoring was a useful tool for CSC integration Integrated, maintained, and validated with ATLAS software CSC reconstruction software validated (Sep 2009) CSC reconstruction and monitoring enabled at Tier0 (since Oct 2009) In mid-December all offline muon detector monitoring was off – problems and solution still unclear Developed associated configuration (DQMF / OHP for online) DQMF/ HAN for offline) for web display Algorithms to extract information from histograms for DB storage Calculation and DB storage of online and offline DQ flags tested (Nov- Dec 2009) Provided documentation on ATLAS and ATLAS Operations twiki’s CSC DQA Status 1

CSC Online DQA Results Run 125032 Layer maps Run 125032 Sampling time Run 125032 Status flags 2 Overall DQ flags extracted for two DQ regions: CSCEA and CSCEC SHIFTONL flags are propagated to database Shifter documentation at P1 up-to-date Check list for shifters provided
3
CSC Offline DQA Results 3 o Overall DQ regions CSC[EA/EC] o Algorithms to identify o dead/noisy layers o outliers o DQ Flags are stored in offline DB o Documentation provided o For Tier0 shifter and o Muon Offline DQ experts
4
DCS Data Quality 4 HV for each layer LV for chamber L1 (Ar) and L2 (CO 2 ) Ratio DCS calculator: overall DCS DQ flags
5
Summary 5 All aspects of CSC Data Quality functional Tested at P1/Tier0 during cosmic /collision runs Work in progress on how to best use the DQ info in reconstruction Need more shift experience in combined runs Modify/ improve and maintain software, shifter histograms, documentation on regular basis (as we gain experience)
6
To Do 6 There are two areas where we need improvement Online monitoring using the calibration stream Perhaps there is a gain in statistics over the current GNAM monitoring Software for calibration stream exists but needs to be tested and integrated at Point 1 Monitoring / rootuple production at the calibration centers For CSC, these are useful for reconstruction studies rather than calibration Again, some software for monitoring and rootuple production exists but needs to be tested and the loop closed Manpower / priority a problem with this item
