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 Layer maps Run Sampling time Run 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

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

DCS Data Quality 4 HV for each layer LV for chamber L1 (Ar) and L2 (CO 2 ) Ratio DCS calculator: overall DCS DQ flags

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)

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
