By the grace of the Universe you already are at 30 deg and 1.3 GeV/c with HMS
1. Restore beam:
a. With raster off insert YAG and check the beam spot. Should be nice and round - not at all like a comet!
b. With the beam at the optimal positions found before (check the white board) take a C-hole run with 3 x 3 raster to check the beam centering on the target. If it looks good move on. If not, center the beam.
2. Request Ion Chamber Calibrations for Optics targets 1 and 2
3. Take large Ytar and Xptar/Yptar HMS optics data
a. Raster should be off and you should switch to sieve collimator for HMS
b. Insert target Optics 1 and take 30 minutes runs at 10 muA with HMS Hodoscopes discriminator thresholds at: 30 mV, 20 mV, 40 mV and 50 mV. (Expert: Simona M.)
c. Insert target Optics 2 and take 30 minutes runs at 10 muA with various thresholds for the CER and PRESHOWER PID legs of the trigger (Expert: Eric P.)
aa) Cherenkov Threshold: 40, 30, 20 and then optimize
bb) PrSh Lo: 40, 30, 20 and then optimize
cc) PrHi: 60, 50, 40
dd) ShLo: 40, 30, 20
