    Day shift summary:

    shift workers: J. P. Chen(SL), E. Khrosinlova (TO), L. Weinstein

    8:00 production on Pb target at Kin02
    around 10:50 left ioc frozen, after reboot, the control screen on hacsbc2 did not come back. Medm frozen. After logout and re-login in,
    re-started medm. control is ok. Left NMR lost lock during the reboot.
    Field drifted. Stopped run 1205. After field set, started run 1206.
    Restarted strip chart for bpms.
    13:15 change spectrometer angels to L=21.44 and R=54.1 degrees.

    13:20-14:45 beam off
    15:38-16:00 beam off, MCC to tune beam to improve beam quality.


    production runs, 53 uA on Pb at Kin02 (L angle=22.41)
    Previous accumulated charge: 0.0.148+0.156+0.157=0.461 C
