    Owl Shift Summary

    00:00 - shift started with no beam on target due to accelerator problems.

    00:45 - beam restored to hall. Alignment checked on BeO and was way off. Nominal positions restored. Harpscan performed. Move to holey carbon to check rates against empty rates. Beam was very unstable during this whole procedure (lots of trips).

    02:30 - target moved to Ta for calibration data.

    03:00 - target moved to Carbon for calibration data.

    03:15 - HRSl set to 1158 MeV/c. Target moved to LH2 for elastics calibration data.

    03:45 - HRSl set to 1007 MeV/c. Prescales changed. Optimal running conditions found at 2.5 microamps.

    05:50 - beam taken away due to problems with electron gun.

    07:35 - beam restored to hall. Positions were way off. Moved to holey carbon to restore nominal values and check rate.

    08:00 - shift ended during run 2893. Stable production running resumed.

    Production runs:
    2886 - 2891, 2893
