keyword=Compton rates at low beam currentThe Compton looks alright at low beam current (thanks to the extensive tuning work today)! Both DAQs can see a signal/background of 9/1, which is great. It looks like there is still a lot of low energy background, though, because the current in the photon detector base (the blue-green line) is not stable during beam trips, and we cannot run like this at higher current. This could be due to the Compton beamline vacuum problem.
