    SUMMARY:

    taking production data with 120 uA beam on "thick" 9Be target


    DETAILS:

    start shift with production run #2982
    ~ 100 uA on thick 9Be target
    16:30 alarm: LeCroy HV MF2; Slot 15 Compton #10
    16:45 Rich HV trip
    16:59 asked MCC what the raster size is: result 0.55x0.55 mm
    (the run sheets show 0.7x0.7 mm since this morning, we did not
    believe that, so we asked).
    18:30: TS problems since some (?) time; restart Coda
    19:18: RICH HV trip
    20:10: Hall C and MCC inform us that the half-wave plate will be changed now
    21:20: scaler readout somehow scred up; call Bob Michaels, he suggests
    to reboot TS2; rebooted all Coda componenets;
    (details see separate log book entry #120047)
    scalers now counting but only visible when logging
    in from external terminal; something screwed up with SUN's window.
    Note: several runs may have scalers missing or corrupted (see entry 120047)
    22:14: Rich HV trip
