    · 08:00 Good morning, Hall A! Starting shift in HAPPEX Production mode. It's nice when things start out working. IHWP=OUT, Slug #19


    · 09:55 Changed beam current to 15uA for Compton work.


    · 10:22 Changed beam current to 100uA. Starting Production Runs.


    · 10:50 LeCroy HV Alarm sounded from Card 11, Channel 1. Turned off and back on. Problem fixed.


    · 12:35 Compton ROC 6 stopped responding. Attempted reboot, failed. Tried again, failed. Called RC and expert to look at it. Running HAPPEX production but not Compton.


    · 13:15 Called MCC to go to Controlled Access to move the Compton Detector closer to the beam.


    · 13:48 Compton work done, going to Beam Permit.


    · 16:00 Ending shift in Production Mode. Good luck, night owls!
