    Swing Shift Summary
    ================

    Crew;


    S.L : M. Dlamini
    T.O : M. Jones
    3rd : T.N. Gautam
    ================

    Time-line;

    16:00 ; Begining of shift, NO BEAM.
    17:30; Hall moves to Controlled Access, Definately no beam for approximately
    the next 1-2 hours.
    M. Jones Changed GEM detector gas bottle the controlled access mode
    Kalyan fixed T1 scalers


    18:40; Everyone out of the hall, we are still in controlled access
    until MCC is ready to go to beam permit.


    20:00; Hall still in Controlled access


    21:00; Change of Run plan by MC::: (1)Crew to start with empty
    target,establish 2 micro A, check BPMs are zero within 1mm on
    BPM4D and BPM4D.
    (2) Establish raster, still with no target - ask for 4x4 and
    with verify spot_L. Use only T8 with LHRS, ps8 = 100
    (3)Put BeO and ask for 2 micro A. Switch off target camera light
    and try to see beam spot. - check T1 rates, should be few KHz, NOT
    MHz
    (4) Centering - Call MCC to move beam up/down/left/right by about
    3mm and check for spikes in the trigger rates. If rates spike,
    then beam is probably hitting a frame.
    (5) If satisfied with beam, then ask for 5 micro A and observe
    the T1 rates. they should linearly increase with current.
    ==>Continue run plan with carbon target WITH NOMINAL BEAM POSITIONS
    i.e +/- 1mm


    22:00; Hall changed from Controlled access to beam permit

    22:24; Call from MCC crew chief. MCC working on Optics to get beam to
    hall. We probably won't be getting beam tonight.


    Target very well behaved tonight!!!!

    00:00; End of shift, No beam
