    Entry number 205975

    keyword=Day Shift Log

    08:00 Start Shift with 6% radiator in, 3He target, 30uA beam and a
    spurratically high dead time problem. In Honor of this problem, we will
    keep run numbers with comments in this log entry as well as on the run
    sheets.

    08:25 MCC called to let us know that they were taking the beam away at 08:30

    09:53 Removed target and radiator to accept tune beam

    10:08 MCC to send CW to hall

    11:20 MCC has restored beam, restoring running conditions.

    11:43 Requested 30uA on 6% radiator & 3He target

    13:12 HRS-L Q3 has started its afternoon drifting! Effected run # 1368.

    13:57 Run # 1369 also suffered drifting of HRS-L Q3.

    14:50 Changed to radiator out.

    15:46 Smoothly running with the radiator out, soon to put the radiator
    back in. The dead-time problem of yesterday through early this morning
    seems to have mysteriously resolved itself just as mysteriously as it
    appeared.

    16:00 Changed to radiator in and requested 30uA. Handed off to the swing
    shift!
