keyword=Comton 15uA run summary
Requested 15uA by closing the slits
Moved electron detector to -2.0mm.
Run 20301: Electron only run, prescales 100%, FADC trig on edet, 3 plane coincidences. Beam halo is at 12, so we will move to 1.0mm and take coincidence run.
Edet moved to 1.0mm
Run 20302: 15uA coincidence run, prescales all at 100%, FADC trig back to the PMT, still 3 plane coincidences. Background is 500Hz/uA, signal is 1200Hz/uA at HV = -1800. Run ended automatically after 20 minutes because of the size limit.
Edet moved back to garage.
