    keyword=Owl Shift Summary


    00:00 Run 1241 is on.

    00:20 Kinematics 8:
    Beam Energy: 3.307 GeV
    Electron Angle 25.50 deg
    Electron Momentum 2.462 GeV
    Recoil Angle 44.33 deg
    Recoil Momentum 1.514 GeV

    Download trigger. Cycled Left Q2/3. 9 uA beam current.
    Noticed that Right Bogies are not changing "PSM ENABLE" to "YES"
    Rebooted the Right ARM iocha16 but did not help. Anyway, before
    getting stuck the Right Arm was at the anlge we wanted.

    Run 1246 Hydrogen Target PS1=5; PS2=700; PS3=6, PS3=40; PS5=1
    Start 01:42; Stop 01:44; Number of Events=50 K.

    Run 1247 Hydrogen Target; PS unchanged
    Start 01:44; stop 02:14.

    Run 1250 Dummy Target, PS unchanged
    Start 02:34 Stop 02:50 ; Number of Events = 145 K

    Moved to Hydrogen target: 10 uA, T2 = T4 = 3 T{1,3,5}.
    T1 = 1000 Hz PS1 = 15
    T2 = 14000 Hz PS2 = 70
    T3 = 1500 Hz PS3 = 20
    T4 = 800 Hz PS4 = 4
    T5 = 500 Hz PS5 = 7

    03:00 - 04:00 Run 1251
    04:00 - 05:00 Run 1252
    05:00 - 05:35 Run 1253
    05:38 - 05:50 Run 1254 Coda crashed
    05:54 - 06:55 Run 1255
    06:56 - Run 1256


    Continued on ep elastic calibration runs.
    Could not move HRS-R for ep kinematics #9.
    Decided to stay at kinematics #8 and do
    the runs with T2 and T4 predominantly triggers
    (for scintillator efficiency studies).
