keyword=Compton electron detector runs
Compton tune was good with photon. Though I only got like 30 minutes for
edet right before access.
I had to play with threholds but could not see the Compton edge.
I still need to look through the data I took to try to optimize
thresholds. But so far I have not seen good compton events from electron
detector ( no change laser on /off ).
24961 HV ramping
24962 good run 25 k events
24963 Good run threshold too
24964 changing threshold from 64 to 7*16
24965 7*16 thres
24966 edet moving
24967 edet moving to 7 mm
24968 edet 7 mm threshold 0x70 1 plane trigger
24969 2 plane trigger 0x40
24670 same
24671 Left thresh A C D to 0x4f
24675 Left thresh D 0x4f
24676 same
24677 same
24978 same 64 channels
