  1. CAF shifts and procedures Marcello, Raffaello, Alberto, Pigi, Sungeun, David, Silvia, Anna & all the 2009 shifters

  2. Goals, tools and shifts • Goal: give a very fast feedback about the run quality • Tools: use online and offline data • Online: DQM, Noise Monitoring, WBM • Offline: DQM and Prompt Analysis • Meeting: short daily meeting at CAF (shifter + leader + expert if needed) • Shifters: 2 people + 1 CAF leader per wee • Documentation

  3. What we can analyze today • Problematic chambers: • Quantify them • Dead or masked (DQM state machine) • Noisy (DQM and Monitoring) • Bunch crossing: • Distribution per wheel/disk (DQM) • List of “not in time rolls” (PA) • RecHits studies: • Average # of cluster per endcap/barrel (DQM) • List of chamber with cluster size > 2.5/3.0 • Efficiency (if possible): • Average efficiency per wheel/disk (PA) • List of chambers with eff. < 85%/80%/75% (depends on HV)

  4. What we do after the analysis • Check results with CAF leader • Write ELOG report per run based on a standard format • Write “special” ELOG message in case of evident problems (after comparison with previous runs) • Call P5 and Shift leader in case of “big problem” or “not understood” results

  5. Where we are & to be done • Documentation and instructions (thanks to the group and to the shifter feedback) • Uniform ELOG reports • Good interaction with P5 and Run coordinator • WBM (Raffaello) • Historical DQM (Anna and David) • Less info to write in the ELOG • More trained shifters (just question of time)
