    Start of swing shift on Oct. 20, 2000
    from 16:00 t6o 17:00, beam tuning activity
    end harp results: 171 times 163 microns (run 1099)
    17:00 tune for Compton
    ffb on, harp results 165 times 178 microns (run 1200)
    17:55 Compton requires Hall access
    swap beam line HV syupply with the GEp calorimeter HV supply
    19:10 we are still waiting, hall open.
    20:00 replacing HV crate on beam line was not successfull.
    20:25 everybody out: beam line HV are now read on hac 42, everything else disconnected.
    as both hall B and C are closing, we expect delays in restarting.
    21:30 we take the electron detector of Compton out of the way.
    beam will continue going thru the chican unless trouble develops.
    Move target to 4He.
    21:45 ramping beam to 90 microA
    22:05 start first run, 1952
    beam trips every 10 minutes on average
    beam taken away by MCC for work on injector..
    end 1952 at 23:10.
    no beam to midnight.
