Shift Summary for eve shift, 19/jun/99

On Shift: Mike Arenton, Rick Kessler

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
Hours of special runs (laser scans, muon runs...):

Accounting of lost time:changing tapes, accelerator down

========================================================================
Runs ended this shift:
Run 13666 - 6.3M events - BEAM_832 - 11.7K vacuum 2pi0

Tapes brought to FCC this shift:, ...
(including tapes for online split)

========================================================================
Accesses during shift: none

========================================================================
Overview of shift:
Accelerator off due to ground fault in feeder cable at beginning
of shift.
Beam returned at 17:30, and has been good and steady for the
rest of the shift, and E832 data was taken with no problems.
There was some roll of the beam due to instabilites in NM2EU.
It is now a few wires at NM2SEED2. Related to this is some studies
R.K. is doing that seem to indicate East/West intensity differences
that may be a function of beam position at the target.
