Zhen YAN, Muon Offline DQ meeting, 05/10/ I added “MS_CSC_EA_DISCONNECTED_2” defect for CSC since AL05 layer 3 and 4 channels (1-96) dead. Relevant ELOG entries : 6https://atlasop.cern.ch/elisa/display/ Problem didn’t appear in later runs.

Zhen YAN, Muon Offline DQ meeting, 05/10/ No major issues.

Zhen YAN, Muon Offline DQ meeting, 05/10/ No major issues except TGC HV glitch. No defects needed.

Zhen YAN, Muon Offline DQ meeting, 05/10/ General issues:  CSC  Link loss problem occurs time to time  MDT  Chamber drop/recovery during the run  Pathological/Disabled chambers during long run (randomly)  ~ 10 MLs consistently have low efficiency(<70%) on BIC & BIA (page 6)  RPC  Feet region sectors didn’t fully functional  Data misalign on sector 25  Tower re-sync  TGC  SSW drop and ROD busy (TGC big storm errors) General comments :  Inconsistent default ranges on some web display plots  RPC coverage plots : BA A13 LowPt1 eta, BC C14 RO HighPt0/1 eta and phiBA A13 LowPt1 etaBC C14 RO HighPt0/1 eta and phi  MDT ML efficiency plots : BIS8A10/A14 BML6A/C13 histogram missingBIS8A10/A14 BML6A/C13 histogram missing  Z axis color scheme is good at efficiency plots but not quiet useful on some occupancy/hit plots due to noisy channel and geometry effect  RPC GlobalHitsPerRPCOuter RPC GlobalHitsPerRPCOuter  MDT OccupancyVsLB_ECInner MDT OccupancyVsLB_ECInner  MDT BEE NumberOfHitsInBAExtraPerMultiLayer_ADCCut MDT BEE NumberOfHitsInBAExtraPerMultiLayer_ADCCut  TGC Strip_Occupancy_Map_A TGC Strip_Occupancy_Map_A  Segments_Z_chamberIndex_perSector Segments_Z_chamberIndex_perSector

Zhen YAN, Muon Offline DQ meeting, 05/10/ Further concerning :  ACR shifter  Offline DQ shifter  Usually offline DQ shifter has to dig out useful information based on the shift summary submitted by ACR shifter which they written with their personal style  Online DQ report is the proper solution and it can be done with good shifter  Sub-detector on-call expert  Offline DQ shifter  Join the DQ meeting every Monday, Wednesday and Friday  Update the detector condition and known problems to DQ shifter in time  Daily summary(like TGC) or Run base summary(DQ shifter) to ELOG  Offline DQ expert  Offline DQ shifter  Specific explanation on those intolerable defects(documents, references and examples)  Optimize/Tuning offline DQ plots  Document more tracking plots(MCP part) if possible My concerning and proposal (just for leading discussion)

Zhen YAN, Muon Offline DQ meeting, 05/10/ Really good and useful DQ report from online Muon shifter “Carsten Bittrich” Could be even better if we specify the template with well pre-defined catalogue/checklist
