    keyword=Shift Summary

    Both HRSs at 17 deg, momentum setting: 3.0855 GeV/c, beam energy: 3.605 GeV.

    08:00 Shift starts with a continuing production in 3-pass.

    09:50 Asked for controlled access while MCC was doing injector work.

    13:30 MCC calls telling beam is coming, and it is. Start checking BPM positions (Specs: both BPM (x,y) = (-0.5, 2.0)).

    13:40 BPM positions ok, asked for harp scan (rastor off).

    13:50 Harp look ok 194 um by 276 um sigmas. Going to do raster scan.

    14:20 Spot check on optics target finished. Going to repeat the same for 3He. While doing for 3He, we are turning BB HV on too. Beam stops now due to RF problems.

    14:40 Beam back, start raster scan on 3He target.
    15:00 Start production on 3He with 10 uA beam. BB HV will still on until any instructions comes from RC.

    15:30 A couple of MCC IOCs went off, beam away.
    15:47 Beam back, starts production. 


    
These are the only production runs on this shift, others are either cosmics or spot check:
