    keyword=Running with BB magnet off - failed

    We tried to run with BB magnet off. The BB detector HV persisted on tripping. We tried:

    5uA, raster on, Feedback on: DC and scint. tripped, PMTs drained 50% more current

    2uA - the same
    1uA, fast raster off: became slightly better
    0.3uA, rasted off, fast feedback off, the scintillators do not trip, but the DC still do immediately
