    Additional Comments:
    08:17 MCC called to send 100 uA to the hall.
    08:40 Called MCC and found out that when fast feedback is on
    it trips the beam off (at 95 uA).
    09:15 Beam seems to be stable now at 95 uA with fast feedback on.
    09:45 MCC called to inform us that when fast feedback is on, it
    tends to increase beam energy that affect Hall C. They
    want to turn FB off to investigate for about 20 minutes.
    09:57 Called MCC to let them know that we finish one run so they
    can remove FB and investigate the problem. It might take
    10 to 20 minutes.
    10:20 MCC finished investigating FB problem. We resume data taking.
    10:33 MCC called they need to reboot injector IOC and like to take
    beam away for 10 to 20 minutes.
    10:53 Beam is back.
    12:48 MCC called to take beam away for about 10 minutes for
    beam study.
    12:52 Beam is back.
    14:25 RICH tripped.
