---|---|
fast raster: | 2x2mm |
targets | 10 cm LH2, 10 cm LD2 10 cm Dummy, C, 10B4C, 11B4C |
trigger | ELREAL |
SHMS collimator: | COLLIMATOR |

Goal is to obtain ~5000 electrons in the range 1.5<x<1.9 for each production target.
- 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.
- Take data on C,10B4C, 11BC at 50 uA. Each target should take about 2.2 hours at 50 uA
- Take LD2 data for 4 hours at 50 uA.
- Take dummy data for at least 1 hours at 40 uA.
