I added “MS_CSC_EA_DISCONNECTED_2” defect for CSC since AL05 layer 3 and 4 channels (1-96) dead.

Relevant ELOG entries :https://atlasop.cern.ch/elisa/display/279106

Problem didn’t appear in later runs.

Zhen YAN, Muon Offline DQ meeting, 05/10/2015 3

No major issues.

Zhen YAN, Muon Offline DQ meeting, 05/10/2015 4

No major issues except TGC HV glitch.No defects needed.

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 phi MDT ML efficiency plots : BIS8A10/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

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, 05/10/2015 9

Really good and useful DQ report from online Muon shifter “Carsten Bittrich”https://atlasop.cern.ch/elisa/display/279560

Could be even better if we specify the template with well pre-defined catalogue/checklist
