    Joe M. and I looked at the EP. We tracked down a bad BNC connector on the
    S2H counter. We replaced that connector. The PMT on the lower cherenkov
    detector seems to be having trouble. Either the base or the tube. Lots of pulses.
    I would think it was a light leak, but Joe said the pressure inside is ok. So, where
    would there be a leak? The gain of S1H seems to be low. We increased the voltage,
    but is still seemed to be off from the gain, and rate, of S1B.
