    keyword=Shift summary

    Saturday 10th November
    Shift:Owl 00:00-08:00

    (1) Shift started with run 1935; the beam position and current monitor GUI displays are still currently down. MCC are going to reboot the gateway (129.57.255.4)
    (2) 00:11 Displays are back online.
    (3) 00:22 Displays have gone down again; MCC say they will remove us from the gateway. 00:42 display has come back online again.
    (4) Display vanished again at 00:46; MCC are considering the problem again. Displays back online at 00:58.
    (5) 01:00 MCC going to do a QE measurement so the beam is temporarily off. Beam parameter displays have gone off-line again as well. 01:05 MCC are having software problems and are awaiting assistance from on-call operators.
    (6) 01:24 Displays are back online - MCC believe they have solved the problem.
    (7) 02:09 Displays offline again; displays back online 02:35.
    (8) 02:41 displays offline again. Displays online again at 02:53. After discussions with the Crew Chief, it was decided that MCC would continually monitor the beam position throughout the night, setting the limits to be < 0.2 mm on both the x and y axes. MCC will also discuss with the software expert on call to have the system looked at in detail in the morning.
    (9) 03:57 BPM displays offline again; MCC will monitor the BPM from now for us.
    (10) 04:30 Unable to get information on magnet cryogenic levels and high voltage details for left/right S0/S1/S2/preshower/shower from GUI displays as these also appear to be down just like the BPM.
    (11) 05:30 ROC1 appeared to crash; stopped run 1955. Reset ROC and the CODA components. Run 1956 seems to be proceeding normally. However, the computer does not seem to have stored the run 1955 data on the log website; the online analysis stopped at around 500000 events.
    (12) 07:48 The high voltage of the Bottom Right Arm appeared to have tripped; restarted logging into HV portserver.
    (13) 08:00 GUI displays now appear to be back online again.

    Last completed run: 1965
