    keyword=shift summary

    Started shift doing 2nd half of delta scan.

    RUN:

    3629 1.519 GeV/c, (+2%) Raster 2x2 11:56-12:15
    3630 1.519 GeV/c, (+2%) Raster 6x6 12:20-12:40

    change to 1.5035 GeV/c

    3631 1.5035 GeV/c (+3%) raster off 00:56-01:15

    change to 1.488 GeV/c

    3632 1.488 GeV/c, (+4%) Raster off 01:30-01:45

    change back to -1%, or 1.5655 GeV/c

    3633 1.5655 GeV/c, (-1%) raster off 02:15-02:40
    Note this is a (useful) repeat of run 3623, where the left septum was accidentally left about 1.5 Amps high. Since we had this in some of our data (again by accident), it is a good measurement to see how it affects the resolution, if at all.


    3636
    right septum set to 148.93 (up 4 amps) to check effect on resolution

    3637 1.550 GeV/c (0%) Bullseye, beam at (+2,0) (-2,0) on BPMA and BPMB respectively. Harp scan was ELOG entry 1212544

    3638 1.550 GeV/c, beam at (+1,0) on BPMA and (-1,0) on BPMB. Harp scan was ELOG entry 1212546.

    3639 beam at (-2,0) on BPMA and (+2,0) on BPMB. Harp scan was ELOG entry 1212548

    3640 beam at (0,0) and (0,0). Harp scan was ELOG entry 1212550

    3641 beam at (0,+2) and (0,+2). Harp scan was ELOG entry 1212551

    3642 beam at (0,-2) and (0,-2). Harp scan was ELOG entry 1212553

    3643 beam at (+2,0) and (+2,0). Harp scan was ELOG entry 1212555

    3644 beam at (-2,0) and (-2,0). Harp scan was ELOG entry 1212556

    Done with bullseye scan.

    05:15-06:20 HAPPEX (Kent and Bryan) are dithering.

    06:20 10 minute run with energy lock off (run 3645). HALOG beam spreads.

    06:40 Ask MCC to adjust 1c12 beam position setpoint -- MCC does not know how. Page Doug.

    07:00 set magnets all to zero current. Beam gone.
