PrimEx Pair Spectrometer Plots
These plots were generated by the CLAS "event_monitor" on run 28754. This data
was taken when there was no beam and the PrimEx dipole was off.
All coincidence levels were turned down to 1 so that we would fire on single
counters. The voltages were also all turned up to -1600V so as to get higher rate.
The total trigger rate from the 20 counters (16 PrimEx + 4 CUA) was a little over
500 Hz. In other words, these mainly come from noise. The purpose of this exercise
was to test that the DAQ was functioning properly.
