keyword=Pion Rejector Layer 1 After HV ChangeThe following figures show the pion rejector layer 1 after the HV
changes Youcai and I made last night. Most of the channels look
reasonably aligned to channel 1000. We did not change the HVs for
ADC channels 15,16,32 and 33, since there wasn't a good peak to fit
from these edge blocks. The HV was tuned using run 2446 taken yesterday
afternoon.
The plots here are from run 2512. We now see a peak from blocks 15 and 32,
so we can now adjust their HV. The momentum for runs 2446 and 2512 was
1.0 GeV/c and 1.174 GeV/c, respectively.
