    Entry number 387698

    keyword=BPM/raster check, part 1

    Plan : check the BPM readout and the raster

    When I arrived at about 3:10, there was 5 uA CW unrastered beam on a BeO target.

    We did a short run with mostly pulser trigger

    Run 1256 / 20270
    beam position is at "nominal zero".
    I think the quads are in a normal config downstream but
    BPM4A at -0.79, -0.35 mm (nominal zero)
    BPM4D at -0.28, 0.81 mm -- this is still called 4B by some GUIs

    Asked to reduce to 2 uA.

    MCC cannot move the beam much without tripping ion chambers at the dump.
    I guess they are hitting the target frame.

    03:30 Put target to empty position. Ask for 2 uA. No raster

    Asked to move beam. Have X,Y = -2, -1 mm
    Runs 1257 / 20271

    03:40 Ask for X,Y = +2, +2 mm
    BPM4A at 0.8, 0.6
    BPM4B at 2.2, 2.4
    Run 1258 / 20272 with these conditions. Plots posted later.
