    Day shift summary

    9.00
    A few alarms on bbps1:2001 L10.02, detectors gas shed (methane) and
    left HRS dipole NMR lock. All are known problems.

    9.25
    Stopped run 3268 early to power-cycle the HV on BigHand layer 6 left-side (bbps1:2008 L11.0 - L11.11) to see if it fixes the problem with the QDC spectra. It did.
    We were advised to power cycle the HV on those 12 channels between stopping and starting runs.

    12:45
    Gas system interlock status alarm for gas shed airflow. Cleared again within seconds. Dipole NMR alarm still goes occasionally. bbps1:2201 L10.02 seems to have settled down.

    15.05
    MCC called to say that the beam will be down for around 30 minutes for injector tests. Stopped run 3273.

    15.25
    Beam back, checks done, back to production running with run 3274.
