    Day Shift Summary
    =================
    Plan: SRC Triple Coincidence Runs

    Kinematic Settings

    * Beam Energy: 4456 GeV
    * Left HRS: 3950 MeV/c, 16.0 degrees
    * Right HRS: 952 MeV/c, 42.5 degrees
    * Target: 10cm 4He
    * Current: 25 μA
    * Prescales:

    * T1 = 70
    * T2 = 1
    * T3 = 9
    * T4 = 1
    * T5 = 1
    * T6 = 1
    * T7 = 2
    * T8 = 15

    Completed:
    8:17 Run 2724 1.3M
    8:45 Run 2725 1.0M
    9:13 Run 2726 1.0M
    9:46 Run 2727 1.0M
    10:18 Run 2728 1.0M
    10:45 Run 2729 1.0M
    11:12 Run 2730 1.0M

    11:15 study of the beam position-target = scan raster size
    beam shift to +1mm in x on both BPMA/B,
    shift beam by +2mm in x direction

    12:05 new beam position is A:(+0.67; 0.30) B:(-1.53; +2.00)
    re-start data taking
    13-14 access to Hall A for T6 investigation
    14:00 beam back
    Spot+ check for beam position - OK 2743
    Investigation is going for BB MWDC and DAQ
    14:55 Run 2747 1 uA for DAQ test
