    16.00 -24.00 Summary
    KF

    1281.....15.58-16.20.....0.3M.....beam disappeared

    16.10-16.35 MCC loaded new steering files, then
    tuned for some time. More FSD trips.

    16.35 MCC informed us that they were having alot
    of RF difficulties and that it would be some time
    before they could come back to us with stable beam.

    16.50 Hall B(C?) requested to modify the orientation of
    the half-wavelength plate. Olivier said this was OK, but
    we need to know the orientation for each run. So when
    MCC calls to say a request has been made to modify the
    plate, stop the run, and start a new one after the change
    has been made. Also, make a halog and a note on the
    runsheet. This procedure will begin around 23.00.

    17.05 MCC informed us that the beam was back. When
    we went to start the run, TS0 would not prestart. Did a
    `kcoda' and restarted runcontrol. Several runs are thus
    junk:

    1282.....junk
    1283.....junk
    1284.....junk
    1285.....test

    1286.....17.23-17.45.....0.3M.....early end due north linac problem
    1287.....18.04-19.11.....1.0M.....beam rather unstable
    1288.....19.12-20.00.....1.0M.....much better beam

    19.25 hiresxt21 required a power cycle. See 52028
    and 52029. We got everything started again. Estimate
    we lost 8 minutes of beam from 19.00 to 19.30 from
    our stripline charts. This info was lost to the power cycle

    1289.....20.01-20.51.....1.0M.....good
    1290.....20.52-21.42.....1.0M.....good
    1291.....junk.....ended run so half-wavelength plate could be inserted



    1292.....21.48-22.22....0.6M.....ended run to remove half-wavelength plate



    1293.....22.23-23.15.....1.0M.....good
    1294.....junk.....ended run so half-wavelength plate could be inserted



    1295.....23.25-
