    keyword=day shift summary

    8/29/05 day shift
    J.P. Chen, D. Higinbotham.

    8:00 taking production data
    8:40 right Q3 tripped due to helium level low quench fault.
    Q1 helium level also low, but did not trip.
    Helium level came bakc ok. Q3 quench fault could not be reset from
    the counting house. Need an access. Will wait until beam study.
    9:00 beam off, beam study (for the remain of the shift?).
    9:30 Hall A in controlled access. Bryon is working on detector.
    I reset right Q3.
    11:30 Bryon completed his work, came out of Hall A.
    MCC said there will be some time before they need to have the hall closed (around1-2 pm?). So let the Compton and Moller people into
    the hall to do some work (~ 1 hour).
    13:30 Q3 tripped one mroe time due to helium level. Reset fine.
    13:30 All work completed in the hall, back to beam permit.
    16:00 MCC ready to deliver beam


    4824 7:30-8:26 100K.
    4825 8:40, 20K, right Q3 tripped near the end.
    4826 8:41-9:00, 34K, left only run, right Q3 is still off.
