Entry number 344914

16:00 Shift starts on LD2 target with DVCS runs at 60 minute intervals
and Compton runs at 30 minute intervals.  We need to wait about 45
seconds between the end-of-run summary acknowledgement and the start of
the next run to allow the acknowledgement to be written to the logbook. 
Current to hall at 2.9uA with acceptable beam positions on all four
monitors.  Run starts with DVCS run #9743 and just started compton run #
24606.

20:39  MCC called to let us know they are sending tune beam because they
have a magnet trip they need to solve.

21:00 Compton problems.  First symptom, no Compton rate, but the laser
was switching.  Then the laser stopped switching. Rebooted CODA.  All
better after rebooting CODA.

21:15 Rebooted calorimeter IOC.

22:55 Noticed beam current drift down to 2.7uA.  Requested 2.8uA but
accelerator seems to be having problems delivering it.  Returned to 2.7uA.

23:44 Current seems to have sagged again, down to 2.6uA.  Called MCC to
see if we can bring the current back up to 2.8uA.  Improved after adjustment.
