- Conditions: SHMS only.
beam current (uA): | 50 uA |
---|---|
fast raster: | 2x2mm |
target: | 10 cm LH2, 10 cm LD2 10 cm Dummy, C, 10B4C, 11B4C |
SHMS collimator: | COLLIMATOR |
SHMS trigger: | ELREAL for physics data taking |
SHMS angle/momentum: | 13.11 deg / -8.5 GeV/c s |
Goal is to obtain ~5000 electrons in the range 1.5<x<1.9 for each production target. 1. Take ~1-2 hours of LH2 data to verify the position of the elastic peak at x=1. If not at x=1, correct count estimates to account for this. 2. Take data on C,10B4C, 11BC at 50 uA. Each target should take about 2.2 hours at 50 uA 3. Take LD2 data for 4 hours at 50 uA. 4. Take dummy data for at least 1 hours at 40 uA.
