    keyword=Compton FADC config chang

    The prescale value for the Compton FADC DAQ was changed to prescale_triggers=5 from prescale_triggers=1. I am concerned that changing the prescale value to too high a number will reduce my laser off background data, so this is something we will have to watch. This prescale value should be fine, though, since we are getting 2000 triggers per mps for laser off and taking 300 sums per mps.
