    Owl shift, Jan 20/2004 (00:00 - 08:00)

    SUMMARY:
    Took production data with frame-target (incl 120 Hz data) during first half of the shift.
    We had some trouble with the beam position stability. Switched back over to Empty target
    during latter half of the shift. However, linac problems limited the amount of empty
    target data taken. We switched over to Moller data mode towards the end of the shift.

    00:50 Killed and restarted CODA processes because of problems following 120Hz running.

    01:57 Beam trip.

    02:20 Problems restoring our beam positions after beam trip. Positions erratic (operators
    retuning our beam positions). Take data as MCC tries to fine-tune our beam positions.

    03:25 Re-established what we believed were reasonable beam positions for data-taking with
    the frame-target (see Silviu's log entry, #73808, for details).

    05:30 Switched back over to Empty target. Beam OFF due to linac problems.

    06:55 Beam back on. Taking empty target data.

    07:28 Set up for Moller run.

    07:48 More problems with linac, no beam.
