  1. July 2011 WHCAL Test Beam Analysis Update on Pedestals & Noise A few event displays Damien Prieur - W-HCAL analysis meeting

  2. Stability – average per run • Slide from last week • Average/RMS per run -> bias depending number of pedestal blocks per run Low stat runs Non uniform pedestals calibration runs ‘shift in pedestal for slot19 FE0’ Electron runs Damien Prieur - W-HCAL analysis meeting

  3. Stability – average per pedestal block • Average/RMS per pedestal block (500 events) • Higher spread of <ADC-pedestal> but more relevant results 361471 361400 Damien Prieur - W-HCAL analysis meeting

  4. Stability – single layer (3) Damien Prieur - W-HCAL analysis meeting

  5. Stability – run 361400 <ADC –ped> Damien Prieur - W-HCAL analysis meeting RMS

  6. Stability – run 361471 Damien Prieur - W-HCAL analysis meeting

  7. Stability – layer 33 • Energy sum run 361473 • Full calorimeter • Without layer 33 Damien Prieur - W-HCAL analysis meeting

  8. Event display – run 361473 Event 2634 Damien Prieur - W-HCAL analysis meeting Event 6999 Event 4734

  9. Summary • Pedestals are fine • Some stability problems with layer 33 • but no dramatic impact on physics • Stable noise • Low nHits/cogZ events • Look like genuine particles… Damien Prieur - W-HCAL analysis meeting
