    Yawei Zhang (TO)
    Chunhua Chen (3rd)
    Beam 3606.4 (HALLA:p)
    Left arm 3.35 GeV/c 12.5 degrees
    Right arm 3.0855 GeV/c 17 degrees
    Plan:16:30 controlled access for Compton (~30 min)
    19:00 insert 1/2 wave plate
    Vince changed this to 20:00 after consulting Hall B

    otherwise: production running

    16:30 called MCC for controlled access
    17:45 Out of Hall restoring beam
    17:52 Beam Permit
    17:56 Sending a few micro amps CW
    18:10 Beam looks good (Spott++) putting in reference cell (D2)
    18:16 asked for 14 microAmps
    18:42 back to production running (after NMR measurement)
    19:41 started new HAPPEX run (31533)
    20:00 Put half wave plate IN retarted HAPPEX (31534)
    20:04 MCC having trouble with the gun (runs stopped)
    20:43 Beam comes back for a few seconds,
    false alarm they're still working on it
    21:01 trying again to get beam
    21:09 Beam is back!
