On Shift: Rick Kessler and Ruth Pordes [and Margaret]

Hours of beam delivered at all intensities: 6.5
Hours of beam delivered at nominal intensity: 6.5
Hours of E832 data (special runs not included): 6.2
Hours of special runs (laser scans, muon runs...): 0.0

Accounting of lost time:
- beam down for 2 hours and
lots of kfrends near the end of shift

========================================================================
Runs ended this shift:
Run 14345 BEAM_832 - 22.5K vac 2pi0
Run 14346 BEAM_832 - in progress
========================================================================
Accesses during shift: Now way!

========================================================================
Overview of shift:

Inherited BEAM_832 run 14345.
Ocassional DAQDEAD_SEC of a few seconds. One process on ktev1
is taking 10% more time than the others. The monitor plane
CPU seems a little high so I increased slightly the B01 and B02
monitor pre-scales in dest/BEAM_832.
