    Shift Workers: J. P. Chen (SL), P. Zhu (TO), E. Fuchey (3rd).

    8:00 Beam study from 7 am to the end of this shift.
    Hall in restricted access. Target magnet ramped down to 0. Septum magents off. Hall A radiation full survey (Elog entry 1778689) Levels are very low: two orders magnitude smaller comparing to Hall C (Elog
    1778692).

    List of hall activities:

    Target rotate from 6 degree to 0 degree (completed)
    Will stay at 5 T. Target material will not change.

    Chicane change from 6 degree, 5T at 1.157 GeV to 0 degree, 5T, 2.3 GeV. (Straight-through). Completed by ~ 10 am (See Elog 1778805).

    Tony checked the harps and lubed both harps.
    FZ1/FZ2 power supplies locked out. Per Yves' request, they will stay locked-out (with Hall A administrative lock) for teh duration of this configuration.
