    08:04. MCC called: beam is taken away for beam studies. Stop run 9400 (285K events). Moved the target to empty position and decreased the loop2 fan frequency to 24 Hz.
    08:25: We are in controlled access.
    13:12 Hall back in beam permit.
    14:41 MCC called: they are sending tune beam in the Hall.
    14:46 MCC ready to send CW beam. Requested 5uA. Set back the fan frequency to 48Hz for loop 2.
    14:51. Acceptable beam with BPM reading in specs. Requested a harp scan.
    Harp scan showed that beam is narrow for x (4b x=0.05). Asked for beam x-size to be increased.
    15:23 Beam size acceptable. We move the target to loop 2 (15cm LH2)
    15:29 Target in beam. Requested 1 uA.
    15:30 Start run 9418 (NOT a production run. Alexandre C. is testing the new trigger)
    15:37 Noticed that the beam position is off for BPM 4b (0.23). Called MCC and asked to zero it.
    15:41 MCC called: they will close slightly our slit in order to get a better current regulation.
    15:54 Start test run 9421 (previous runs were tests too)
    15:59 Asked MCC to turn beam lock on (since Hall C is down, there is no conflict with their lock)
