    Shift Summary

    0800: Q2 Right arm tripped, Controlled access to reset from Hall A
    Move to 12C target, Raster at target to be 2x2, 1 uA cw beam
    0907 Q2 Left arm tripped. Leave it as it is, reset it later.
    MCC recycling Moller quads.
    0927: Mcc is able to send 1 uA cw. We will check beam size with OTR, SPOT++ and harps.
    0940: Run 1272: Checked raster spot size 2x2. Harps 1940 and OTR look good.
    Going to Empty reference cell and check low momentum setting (0.5 GeV)
    0947: Run1273: Checking coil temp. at different currents. 0 uA - 6.3 K
    3 uA - 6.3 K
    1015: 5 uA - Temp keeps rising. stopped at 6.7K.
    Now repeat this with the Pol 3He target.
    1020: Run1276: Checking coil temp with Pol 3He target.
    Again at 5 uA the temp starts to rise.
    1044: MCC going to pass change for Hall C
    1110: Controlled access to look at target
    1200: fire alarm tests.
    1420: Q2 right tripped off when changing momentum.
    1430: asked for controlled access so technician can take a look at Q2R.
    1440: Q2 has been resetted from countin house finally.

    1530: Right HRS Dipole has settled. Ask MCC for 1uA unrastered beam on BeO.
    1535: Run 1278, BeO target, raster OFF. 1M events
    1543: Run 1279, BeO target, raster ON. 1M events
    1548: Going to Empty Target to check rates.
    1556: Run 1280, Empty target, Raster ON.
    1600: Run 1281, ""
