    shift summary 12/05/01 16:00 - 24:00

    16:00 shift started while taking data on run 2853. Kinematics G_I_+
    17:55 MCC called: beam down for few minutes
    17:58 MCC called: beam is back
    19:30 Trigger efficiency run for kinematics G_I_+
    19:40 We decide to go back to kinematic G+ to see if the p-shell peaks are shifted
    with respect to those found at kinematics G_I_+ (see halog entry # 78788)
    Right arm Hadron Momentum change : from 0.991 to 1.066 GeV/c. We did cycle the quads
    20:15 Start run nr.2859 of kinematics G+
    21:37 End run nr.2859 and start to change Right Arm Hadron Momentum
    down to 0.916 GeV/c
    22:10 Start run 2860 : KINEMATICS G_II_+
    prescalers left at : 114/16/2400/240/1 dead time 4%.
    We are going to djust better the prescaler the next run.
    header file hdr_king2+ created
    00:00 Leave run 2864 running to the next shift
