  1. DT calibration software:tentative release schedule S.Bolognesi & S.Maselli & G.Mila Alignement&Calibration Meeting, 25 January 2008, CERN

  2. Noise DB • Noise channels computed from random trigger runs or normal runs (looking for hits outside the allowed time region for muon signal) • noise channel if number of hit > tuned threshold • Algorithm implemented in CMSSW and systematically tested on sector/wheel commissioning data • TO BE DONE (short-term) • separate the algorithm to compute noise channels from the full offline noise study (as a function of time and space) • card in cfg to switch on/off the full study • implement the writing of the DB • DB noise interface already exists (DTStatusFlag) 2 AlCa Meeting – CERN 25 January 2008 S. Bolognesi (INFN To)

  3. Test pulse runs Test pulse signals for a given wire • inter-channel synchronization comparing peak position in each wire good test pulse signals electronic noise due to enabling/disabling masks • possible long-term DEVELOPMENT: use test pulses also noise to monitor noise channels to monitor dead channels (made by hand until now) 4 AlCa Meeting – CERN 25 January 2008 S. Bolognesi (INFN To)

  4. Time pedestals derivative of the rising edge fit with a Gaussian (<t>, s) TDC spectrum ttrig = <t> - k × s • <t> and s computed from the fit and stored in DB with SuperLayer granularity • k factor tuned from residuals Theta SL Phi SL time pedestal (ttrig) • TO BE DONE (mid-term) • implement automatic k factor optimization • plotting residuals with the needed granularity • it will be the starting point for validation (based on residuals) 3 AlCa Meeting – CERN 25 January 2008 S. Bolognesi (INFN To)

  5. Summary • Development foreseen on • short term (by the end of February → inside CMSSW_2_0_0) DB writing in noise analysis • mid term (by the end of March) k factor automatic optimization (→ kick off for the validation) • long term use test pulses data to compute noise and dead channels 5 AlCa Meeting – CERN 25 January 2008 S.
