    keyword=Optics run plan

    Tonight we will be taking a Q2 run, bulls-eye scan, and optics data. So the plan is:

    1. Change into Counting-mode and take a Q2 run.
    2. Move the target out, ask MCC to turn off the raster, then turn off the raster power supply.
    3. At 4uA take a bulls-eye scan for BPMB at nominal, +/- 1.5 in X, +/- 1.0 in Y.
    4. Make an access to rotate the sieves in.
    5. Take optics runs at +1%, +0%, -1% (for Carbon) with the sweeper ON and OFF for the Single foil Carbon target, Single foil Ta target, and the +/-12cm and +/-6cm multi-foil targets.
    6. Restore the raster
    7. Restore for production running

    The momentum settings are determined by just scaling the standard production-settings. For E0=3.1812 GeV, at 6 deg E' for hydrogen is 3.12316 GeV and for carbon it is 3.17625 GeV, for a ratio of 1.017. So:

     Setting    L_HRS(P0/Isep)         R_HRS(P0/Isep)
      +1%      3.2083 / 332.40        3.1972 / 325.53
      +0%      3.1765 / 329.11        3.1655 / 322.31
      -1%      3.1447 / 325.82        3.1339 / 319.08
