    keyword=Shift Summary - Owl, 6/20

    Shift summary, Owl 6/20:

    00:00 - In production at start of shift, run 4716

    00:30 - LeCroy beamline crate tripped. Rebooted

    00:50 - ROC6 (Compton) crashed. Went to spot++ not long after, reboot process occured during spot++ the followed.

    01:00 - Production run 4717 ends, start spot++. Left HRS DAQ needed ROC3 rebooted, right HRS DAQ locked up, unsure how to make it run.

    01:30 - Back in production.

    02:40 - Lost Compton rate. In an attempt to diagnose, find that IOCs 11 and 22 (LeCroy crates) crashed, so there no control over the crates. Rebooted the IOCs. Will see if the Compton HV tripped and reboot that, assuming it is what the problem is.

    04:00 - Another spot++. Again, looks reasonable.

    04:50 - LeCroys back, Compton restarted.

    05:50 - Compton crash (ROC6).

    06:40 - ROC25 crash. Do spot++ while figuring out how to reboot it.

    06:50 - Spot looks fine, ramping back up to 70uA.

    08:00 - Shift ends in production.

    Runs:
    Production: 4716-4722, 4726-4727
    Crashes: 4723, 4724, 4725
