    keyword=Work on Q3 finished for now

    Mark Stevens has tried for the last four hours to track down the problems with
    Q3, but he couldn't really pinpoint the cause. It looks like there is an intermittent
    spurious voltage at the output of the Q3 quench signal amplifier, but the origin of the
    voltage is unclear. Grounding problems? RF interference?

    We decide to bring Q3 back up provisionally and give it another try for now.
    If the quenching continues, decisions will have to be made. It was nearly impossible
    to take data under the conditions at the beginning of this shift.
