    keyword=Day Shift summary

    7:45 I arrived in shift as target operator and was told I should also be the shift leader because nobody signed up as shift leader. It is NOT acceptable that I am given a shift leader responsability without any advance notice and for my first shift on a new experiment. Especially, there are enough students on this experiment to avoid this. This is the second times this happens to me in this batch of He3 experiments.

    8:00 Continuing data taking at 10 uA, runs 31310 (happex), 16770 (Compton), 1757 (left HRS), 20663 (right HRS).

    8:02: start runs 1758 (left HRS), 20664 (right HRS).

    8:23: stop compton run 16770. Good run. Start run 16771

    8:45: stopped Happex run 31310, start run 31311.
    stopped L-HRS run 1758 (2M events), start run 1759.
    stopped R-HRS run 20664 (1.49 M events), start run 20665.

    9:34 stopped L-HRS run 1759 (2M events), start run 1760.
    stopped R-HRS run 20665 (1.5 M events), start run 20666.

    10:00 Bob Michael came in and said he will work on the Compton DAQ. He will restore the normal running configuration when he is done.

    10:21 stopped L-HRS run 1760 (2M events), start run 1761.
    stopped R-HRS run 20666 (1.5 M events), start run 20667.

    11:08 stopped L-HRS run 1761 (2M events), start run 1762.
    stopped R-HRS run 20667 (1.5 M events), start run 20668.

    11:20 Bob is done for now with the Compton DAQ. He will need to go down in the hall to fix a crate. So if there's any access during the day, page Bob.

    11:21: stop compton run 16771 (good run), start run 16772.

    11:52 stopped L-HRS run 1762 (2M events), start run 1763.
    stopped R-HRS run 20668 (1.5 M events), start run 20669.

    12:45: stopped Happex run 31311, start run 31312.
    stopped L-HRS run 1763 (2M events), start run 1764.

    stopped R-HRS run 20671 (1.5 M events), start run 20672.

    14:53 Realised we lost the Happex DAQ (the DAQ display disappeared). ==> stopped L-HRS run 1766 (1.5M events) and R-HRS run 20672 (1.2 M events)
    We called back the happex DAQ. The display came back, showing that the DAQ was still running.

    14:54: start runs 1767 and 20673

    15:21: stop compton run 16773 (good run), start run 16774 (short run, end of run failed) and then 16775.
