    3062 16:36 16:47 163K End run to make Hall A access
    3063 21:13 Runs 3063 through 3067 are garbage

    16:29 MCC called to inform us to stop the beam in 5 minutes for Hall A
    controlled access to work on RICH.

    16:50 Beam off. Make Hall A controlled access to work on RICH.
    18:30 Left VDC HV (top and bottom) tripped off. This happened while
    people were working in left arm hut area on RICH. Reset both left
    arm VDC HVs.
    19:25 Both VDC HV on left arm tripped again. Reset them.
    20:55 Power permit.
    21:08 MCC called to give us beam.
    21:10 Beam is back.
    21:13 Runs 3063 through 3067 are garbage runs because left VDC thresholds
    were reset to zero due to HV tripped earlier. As a result, all wires were
    read causing large data stream.
