    17:22 MCC called: They will send tune beam in the Hall.
    17:23 MCC called: They will send CW beam in the Hall.
    17:24 MCC called: They will send 100 uA beam in the Hall.
    17:26: Start ramping current to 100 uA
    Start run 3083. Check beam spot size: ok
    17:46 Beam is down (cavity trip). MCC predicts 10 min of time down. Stop run 3083
    17:54 MCC called: They will send tune beam in the Hall.
    17:57 MCC called: They will send CW beam in the Hall.
    18:04 MCC called: They still have some problems with trips.
    18:15: Tune beam
    18:25: MCC called saying they will deliver 100 uA beam.
    18:30 Beam is back. Start run 3084
    18:32 Beam down Start stop run 3084 is junk.
    18:43 Beam back. Start run 3085.
    19:39 Stop run 3085, start run 3086
    20:32 Stop run 3086, start run 3087
    since ~21:00 the beam is pretty instable and goes up and down. MCC said that the problem comes from the Hall C beam.
    21:20: Beam is down.
    21:38. Beam still down -> stop run 3087
    We will wait for a stable beam before to start a new run.
    21:49: MCC called and said that the will deliver only 50 uA of beam while they are trying to fix the instability problem.
    22:26: Beam seems stable now: Start run 3088
    22:50: Stop run 3088: The DAQ may have some problem (error message reporting that the trigger supervisor and roc did not reported since a few min).
    22:50, start run 3089
    23:50. Stop run 3089. Start run 3090
