    keyword=Shift summary

    08:00 start the shift with 96.5uA in Hall, continue to take production data with a parity run 14139.

    08:41 parity coda crashed, #14140 junk

    12:00 ask mcc for 115uA

    12:55 In the last 55min, beam tripped 10 times, pretty good, continue to take data at 115uA.
    14:20 Observing may trips, asked for smaller current thinking that could help reducing trip numbers.

    15:00 We have now 110 uA and the trip rate is reasonable.

    On an average the beam trip per hour was about 11.

    15:20 PVDIS coda problem: ROC25 failed to respond. After rebooting ROC25, the pvdis coda becomes normal.
