    keyword=Day shift summary

    8:00 Starting the shift. Status:
    *Continuing data taking with production run 12245.
    *No right HRS Q2.
    *No Target Op. (Vince staying until volunteer Mark Dalton arrives).
    *No Compton.
    *No Food for the shift crew.

    9:02 Done with run 12245. Start run 12246. TO M. Dalton arrived (did not know he was volunteered).

    9:59 Done with run 12246. Start run 12247 (although we expect access near 10am).

    10:15 Hall in controlled access to fix Q2 (Jack S. went in). Stop run 12247. Start pedestal run 12248, per Mark Dalton request.

    11:17 pedestal run 12248 finished. Started a new pedestal run, 12249.
    11:28 Stop run 12249: no events: coda seems to be hanged. We killed coda and started over.
    11:50 Coda fixed. Started pedestal run 12252

    12:28 right Q2 seems to work fine now. Jack and Heidi are out. We called MCC asking to lock the hall and bring back the beam.

    12:36 Stop pedestal run 12252.

    12:37 Requested 5 uA to check first the raster. Raster size is 7*5. A little bigger than requested (6.0*4.5).
    12:38 Compton HV trip
    12:39 Short HRS DAQ run for spot++ (run 24696). Eevrything looks good. Asked for 100 uA.

    12:43 We have 100 uA. Start production run 12253 (**with good right arm**)

    13:16 MCC is sending pulse beam to improve the tune in order to reduce the compton rates. Should take ~10 min. -> stop run 12253.

    13:23 MCC done. They are restauring 100 uA. Start production run 12254

    14:20 Run 12254 finished. Start production run 12255

    14:41 MCC called: they will take the beam for a short while to cycle two quads on our line (1HO2 and 1C15).

    14:48 Beam back. Run 12255 continuing.

    15:12 Compton HV trip.

    15:17 Run 12255 finished. Starting run 12256.

    15:47 Compton HV trip

    15:48 Jay Benesh called, requesting PMT HV for scanners 1C18A&B and 1C07A&B to be turned on (MCC have no control of them anymore and want to run the harp for diagnostic).
