    Shift summary -- 0-8h, 13 Dec 00

    00:15 Bad beam. Many trips.
    00:20 Beam off. RF cavity problems and QE checks. End run 1261,
    00:40 Beam has returned. Start run 1262.
    02:00 Still many trips and unstable beam.
    05:02 Rear FPP trip. End run 1266. Resetting FPP HV ends up taking a long time because of communications problems (network?).
    06:00 FPP back up, but no beam. MCC is tuning cavities.
    06:05 Beam returns.
    06:15 HV monitoring script keeps warning us that FPP HV channel 8.1.16 reads 0, but the terminal server readback is fine (1875V). After consulting with Mark, we decide to ignore the script.
    06:45 Many FSDs again during run 1268.
    07:40 Really lousy beam again. End run 1269 early. MCC takes the beam to work on it.
