F2 Large x runplan: February 2019
From HallCWiki
- Conditions: SHMS only.
| beam current (uA): | 50 uA |
|---|---|
| fast raster: | 2x2mm |
| targets | 10 cm LH2, 10 cm LD2 10 cm Dummy, C, 10B4C, 11B4C |
| trigger | ELREAL |
| SHMS collimator: | COLLIMATOR |
| SHMS trigger: | ELREAL for physics data taking |
| SHMS angle/momentum: | 13.11 deg / -8.5 GeV/c |
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.
