Summary for 10/10/99 OWL Shift (Sun.)

On Shift: RickK, EarlS

Hours of beam delivered at all intensities: 0.0
Hours of beam delivered at nominal intensity: 0.0
Hours of E799 data (special runs not included): 0.0
Hours of special runs (laser scans, muon runs...): 0.0

Accounting of lost time:

Accelerator cool down, problems with vacuum isolation valve between
C0 and C1, NM2S3 power supply trips.

Runs ended this shift: none

Tapes brought to FCC this shift: none

Accesses during shift: none

========================================================================
Overview of shift:
Still NO BEAM, too quiet.
========================================================================
Description of Shift:

Shift almost defies description -- we waited.

Actually, we did raise the KTeV vacuum window cover for MCR to
establish beam permit status.

07:00 Mary calls from MCR. The C0-C1 vacuum sector isolation valve
can NOT be opened. Techs have worked on it most of the night,
including trying to open it manually -- no luck. They must
replace valve -- estimated time 24 hours.
