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. 1st and that we will not see collisions before Jan. 1st, 2007. Present situation: cooldown starts on Jan 2nd and we will not see collisions before Feb. 1st.

• 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 – ChiHV 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.
