    keyword=Shift Summary

    8:00 AM - 9:45 AM Left Spectrometer stuck when trying to move it to 14.1 degrees. After restarting several times, it finally moved (When Doug arrived).
    8:45 - 9:00 Run 1585 250K
    9:01 - 9:13 Run 1586 250K
    9:17 - 9:28 Run 1587 250K
    9:32 - 9:44 Run 1588 250K

    9:45 Change to tilted C target
    recalculated prescale factors
    ps3 = 100i ps6 = 2000
    Noticed large 56% deadtime Run 1589.
    Killed run. Started again.
    Increased prescale factors to 200 and 4000. Deadtime reduced to 1%
    Put ps3 back to 100, ps6 =4000 Run 1590. Low deadtime
    Put prescale factors back to 100 and 2000. Still Low deadtime
    Deadtime is okay now. We don't know what was wrong,
    Start again.

    10:18 - 10:31 Run 1592 251K
    10:32 - 10:47 Run 1593 250K

    Moved spectrometer to 15.5 degrees and changed field to 1.14720

    11:12 - 11:26 Run 1595 251K

    11:27 MCC requested beam for 20 minutes for injector studies.

    11:58 Beam is Back

    11:59 - 12:10 Run 1596 251K

    Changed target to 4 cm liquid hydrogen

    12:28 - 12;40 Run 1597 251K
    12:41 - 12:55 Run 1298 251K

    Move Spectrometer to 17.0 degrees
    Changed field to 1.13740
    Set Prescale PS3. PS6 is the same.

    13:16 - 13;29 Run 1599 251K
    13:30 - 13:43 Run 1600 251K
    Changed to tlted carbon target

    13:56 - 14:09 Run 1601 251K
    14:10 - 14:26 Run 1602 251K
    14:41 - 14:52 Run 1603 251K

    15:35 No beam for 10 minutes
    Beam Back
    Turn on Neutron Veto counters high voltage.
    Set ps7 =10000 to chack ADCS
    Left Vetos ADCs 0-7 not working
    Right Vetos ADCs 0-7 not working

    Turn High Voltage for Vetoes off
    Start taking data again

    Changed target to 4 cm LD2
    Cycle Quads Q2 and Q3
    Set Dipole to 1.152 GeV
    Move LHRS to 21 degrees

    Started Run 1604 250K

    16:09 Start Run 1605
