    Shift Summary:
    ----------------------------------------------------------------
    00:00 - S0 tuned on, Happex Left detector HV set to 1900V. Testing new base(H3) on the PMT, count rate etc...(Rupesh)
    00:20 - S0 turned off, HAPPEX detector back to 1600V
    00:35 - Asked for 3.5x3.5 (7.7x6) rater size and 50uA.
    01:10 - 0.5uA to take R_HRS run with S0 turned on.
    01:30 - Asked MCC for 70uA for production
    03:30 - MCC have problem delivering beam. Sending beam to Hall-A dump.
    03:40 - beam back.
    05:56 - Asked to turn off the beam for detector linearity test on RHRS.
    06:25 - Done linearity tests. Back to production.
    06:40 - R-HRS detector saturating. Beam turned off to debug.
    07:24 - Crate re-boot,fixed pedestal to R-HRS ADC, back to production.
