keyword=Optics run plan
Tonight we will be taking a Q2 run, bulls-eye scan, and optics data.
So the plan is:
- Change into Counting-mode and take a Q2 run.
- Move the target out, ask MCC to turn off the raster, then turn off
the raster power supply.
- At 4uA take a bulls-eye scan for BPMB at nominal, +/- 1.5 in X, +/-
1.0 in Y.
- Make an access to rotate the sieves in.
- 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.
- Restore the raster
- 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
