Shift Summary for owl shift, 07.19.99

On Shift: JAG, VJ

Hours of beam delivered at all intensities: 6:05
Hours of beam delivered at nominal intensity: 6:05
Hours of E832 data (special runs not included): 6:00
Hours of special runs (laser scans, muon runs...): 0

Accounting of lost time: beam energy conservation, Linac klystron problems,
KFRENDing.

========================================================================
Runs ended this shift: none, Run 13945 continues ...

Tapes brought to FCC this shift: none.

========================================================================
Accesses during shift: None

========================================================================
Overview of shift:
Took lots of 832 data. Very efficient/boring shift, until klystron
problems killed off the beam.
