    keyword=Shift summary

    8:00 Starting the shift with run# 2495 in progress.

    12:44 MCC called. Their injector expert is here. So they are now going to run some tests.


    12:57 MCC is going to work on the beam spot. So no beam in the hall for 30 to 45 minutes. Start a pedestal run.

    13:20 MCC ready to send beam.
    13:30 Beam current at 10 uA to check spot.

    14:39 FSD trip: MCC is trying to recover now.
    15:54 MCC called. They have an IOC that went bad and experts are coming. They cannot give an estimate of the time it will take.
