    keyword=Compton PMT High Voltage Test Runs

    Test runs scanning Compton PMT high voltage. Beam current is nominally 60 uA. 
Background is ~200 Hz/uA for HV = -2200 V.

60249 - Sampling run. HV = -2200 V. Compare Counting DAQ 14311.
60250 - Integration run. HV = -2200 V.
60251 - Sampling run. HV = -2300 V. Compare Counting DAQ 14312.
60252 - Sampling run. HV = -2400 V. Compare Counting DAQ 14313.
60253 - Sampling run. HV = -2500 V. Compare Counting DAQ 14314. (This run is 
shorter than the others due to Controlled Access.)
