    10:57 am: Start run 5410.
    11:03 am: DT = 100%, Killed coda, ROC9 rebooted.
    11:08 am: Run 5411 started.
    11:45 am: BB DCs 2 and 3 HV tripped again. This happened during a beam current ramp. Stopped run.
    11:52 am: Run 5412 started.
    11:55 am: AGAIN BB DC HV trip. Run Stopped. Called MCC -> still ramping beam slowly
    12:00 pm: Run 5413 started and stoppes immediately after another HV
    trip (BB DC).

    12:15 pm: MCC called to investigate some ion chamber trips in our hall.

    to an "ARC magnet mismatch". MCC called magnet expert to look into it.
