    Details
    =======

    Shift starts with Happex run 13426 at 97uA and IHWP OUT, slug 27

    08:08 Compton GSO HV trips. Turned HV on (was set to -1800V from previous shift)
    08:30 Compton run 20540 crashed, coda restart
    08:40 start compton run 20451
    08:42 Could not prompt runs 13426 and 13427
    08:45 Runbird was complaining about missing analyser. Caused by a stalled Happex CODA.
    Zafar killed coda and did a "startcoda".
    08:49 Start Happex run 13428
    09:15 Started Coda on left arm
    09:24 Spot++ run 25099, raster size on target: 6.5 x 5 mm
    09:41 Computer Center called in and is asking for ~5min downtime for updating webservers. So during the down time
    we would not be able to make any log entries (manual+automatic). A good time would be during beam studies or
    other schedules downtimes but nothing seems to be scheduled for the day shift. Since we have production runs
    I urged CC to call the run coordinator.
    09:45 Starting prompt analysis which apparently crashed during this morning.
    09:46 Start Happex run 13429
    10:32 Start Compton run 20542
    11:50 Changed IHWP to IN, starting slug 28
    11:52 Start Happex run 13432. Dedicated run at 50uA for Happex detector linearity tests
    performed by Rupesh
    12:14 Start Happex run 13433
    13:07 Compton GSO HV trip.
    13:11 Start Happex run 13434
    14:08 Start Happex run 13435
    14:29 Start Compton run 20545
    14:45 After some beam trips beam is off now
    14:55 MCC: A magnet in south linac is down and its power supply must be replaced. There will be no beam for ~30 min.
    15:06 Start Happex run 13436: dedicated pedestal run (beam off)
    15:47 Start Happex run 13437: dedicated pedestal run (beam off)
    16:08 Resuming beam at 98uA
