1 HBD Commissioning (II) Itzhak Tserruya HBD group meeting November 28, 2006 Progress from October 3 to November 28, 2006

2 Pre-beam commissioning (I) October 3: cooldown starts on Dec. 1 st and that we will not see collisions before Jan. 1 st, Present situation: cooldown starts on Jan 2 nd and we will not see collisions before Feb. 1 st. Pre-beam commissioning status: done  in progress  to be done the two detectors installed all cables (signal, HV and LV) connected Gas recirculation system operational  Gas monitoring system – Bob/Craig  UV lamp monitoring -- Sasha/Tom/Craig  readout electronics operational & take data in stand-alone mode – Chi  HV software fully operational – Deepali/Takao

3 Pre-beam commissioning (II) noise optimized  dead channel count  pedestal runs done routinely  timing and data taking with pulser done routinely  data taking with UV-lamp – Sasha/Tom/Craig  ADC charge calibration for all detector modules  first order zero suppression -- Maxim  Monte Carlo simulations basic Geometry and materials in reconstruction up to the pad response  3d map in +- configuration  cluster reconstruction  tracking to HBD

4 Pre-beam commissioning (III)  HBD online monitoring, including: Event display: pad response  Event display: cluster response  Pulse height distribution of a detector modules  Pad frequency vs. pad number  Cluster size distribution  Cluster pulse distribution  Tracking in the +- field 3d field map Very good progress over the last two months in spite of QM and we still have about 2 months to complete this program. I think it is doable in this amount of time.
