    16.00 - 24.00 Summary
    KF

    16.05 MCC called to inform us of hardware problems
    in the north linac.

    1309.....16.12-17.08.....cosmics

    17.05 MCC informed us that they are ready to restore
    our beam.

    1310.....17.18-18.15.....0.8M.....ended run due to poor beam

    17.20 Noticed the Right Arm VDC high voltage is
    oscillating between the correct set value of -4.0 kV and
    a value of about -1.5kV with a very fast time constant
    (about 10 s). I don't think this is real (suspect a
    communication fault), but since the Right Arm is not
    being used and its magnets are off, I turned the VDC
    high voltage off as well, just to be on the safe side. This
    should be investigated at the next opportunity.

    1311.....18.16-19.14.....1.0M.....macroscopic duty about 65%
    1312.....19.15-20.14.....1.0M.....macroscopic duty about 65%
    1313.....20.15-21.11.....1.0M.....md ~80%
    1314.....21.12-
