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

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

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)

What we do after the analysis Check results with CAF leader Write ELOG report per run based on a standard format 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

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)
