keyword=owl shift summary
00:00 in production without right arm.
3:30 move the target to Aluminium dummy for background studies
6:00 compton cavity power dropped close to 0, no more good compton rates, just
background
6:30 informed Alexander about the compton rates, and he is looking at it. he
took over the the daq as well.
6:38 move the target back to LD2
8:00 ask MCC for controlled access for the techs to look at the right arm
magents, and get it fixed
