  1. RPC DQM(new features) A. Cimmino, D. Lomidze, P. Paolucci I.N.F.N. of Napoli Muon Barrel Workshop 20/04/2009

  2. Data Input Algorithm of the RPC SM in 31x HV Status ON OFF Chamber OFF OK % of Dead Strips ≤ 50% ≥ 80% Dead Chamber OK 1 bin Cluster Size 50%< & <80% Noisy Strip ≥ 0.85 Status Colors Partially Dead Dead > 0 & ≤ 5 < 0.85 Partially Dead Noisy strips OK Noisy Chamber Noisy Strip = 0 <#digi> ≥ 6 Noisy Chamber OK Bad Shape < 6 OFF Algorithm still under refinement Occupancy Asym. ≥ 30% OK ! Bad Shape < 30% Good Chamber

  3. Cuts and Colors of summary histograms First Bin ClusterSize 0.0 – 0.75 Green 0.75 – 0.80 Yellow 0.80 – 0.85 Orange 0.85 – 1.00 Red Dead Strips Fraction 0.00 – 0.30 Green 0.30 – 0.60 Yellow 0.60 – 0.80 Orange 0.80 – 1.00 Red Left-Right Asymmetry 0.00 – 0.30 Green 0.30 – 0.50 Yellow 0.50 – 0.70 Orange 0.70 – 1.00 Red Summary Histogram OFF Blue Dead Red Partially Dead Pink Noisy Strip Yellow Noisy Chamber Orange Bad Shape Light Blue Good Chamber Green Multiplicity average 1 – 4 Green 5 – 6 Yellow 7 – 8 Orange 9 – 10 Red

  4. Roll (η-partition) vs Sector plots for all main variable. Standardized color code Easy life for shifter (even if not expert)

  5. TOP LEVEL SUMMARY PLOT Efficiency = 87.5 % (95% ex shape) Misidentification = 0

  6. Study of State Dependence from RPC Events We have to wait at least for 70.000 RPC Events to run at full efficiency the State Machine.

  7. RPC State Dependence @ RPC Events & Efficiency of the SM

  8. New RPC DQM Client Architecture RPCDqmClient • Only 1 EdAnalyzer (RPCDqmClient) configured via _cfg.py • List of tests • prescale factor • histogram folder • Several RPCClientmodules perform the various tests. • Loop on Geometry is done only once in the RPCDqmClient • Use of strings was reduced to minimum terms. RPCNoisyStripTest RPCOccupancyTest RPCClusterSizeTest Timing report for analyzing 13.7* 10^5 RPC Events RPCDeadChannelTest RPCMultiplicityTest TimeReport ------------------------ Module Summary -------------------[sec]----------------- TimeReport per event per module-run per module-visit TimeReport CPU Real CPU Real CPU Real Name TimeReport 0.000000 0.000061 0.000000 0.000061 0.000000 0.000061 rpcdqmclient Gained a factor 6!

  9. RPC DQM FED Information • Recordtypes per FED • Fatal e non fatal errors • Link delay spread RUN 66722 Readout Error histogram EMPTY  GOOD

  10. RPC DQM Short Term Instructions • When a minor problem (no need to stop the run) occurs after the expert has been alerted, the DQM expert fills in the DQM short instructions twiki page : • https://twiki.cern.ch/twiki/bin/view/CMS/OnlineShortTermInstr • Short-term notes/instructions for current running conditions. • Notes here are supposed to represent temporary changes with respect to the normal instructions the shifter was given. • In case of doubt, contact the subsystem expert. • The instructions in this page supersede the Online shifter instructions • Known alarms will be ignored by the central shifter and not cover the new ones. • Good runs will not be flagged as bad (his was an issue during one of the last MWGR)

  11. Conclusions • Major changes made in 3.1.x • RPC State Machine is working properly • tested on many CRAFT runs • (ε ≥ 85% and MissID = 0%) • we can still improve some cuts • All unused plots have been cancelled • RPC quality flag is now defined by SM • All DQM code is ready for Endcap too with exception of the new SM.
