    keyword=VDC high voltage

    The VDC high voltage is back up, thanks to the magic of "not really doing anything".
    Although I toyed with the gas system a little, I did not do anything which would
    affect the VDC operation. We will worry about the high voltage later, if it trips again.
    I note about a 5 PSI drop of pressure in the FPP gas line from the Gas Shed to the
    Detector Stack. The FPP flows were, when I checked: 1 at 53 (53 nominal), 2 at
    51 (57 nominal), 3 at 48 (45 nominal), 4 at 80 (50 nominal). I did not record the
    reading from the little flowmeter, but it appeared to be about the usual setting. I hope
    these are the intended flows. It seems the mixing system is functioning correctly.
    There may be a restriction in the FPP supply line. I suspect the rotameter in the
    Gas Shed.
