Carbon hole target (spot++)
- BPMs for the c-hole target center:
4A (0.5, -3.0) 4E (0.5, -3.0)
- Recent spot++ with 2x2 raster: (slightly off centered by 0.1 in x)
- Raster: 8.5 (width) 2.5 (height) MCC unit -> roughly 2x2 actual at the target
- HALOG
- slightly off centered (x by 0.1) RHRS spot++ result
- slightly off centered (x by 0.1) LHRS spot++ result
Pb#7 target
- BPMs, attenuator setting: HALOG
40Ca target
- BPMs: HALOG
- To get 150k T1 rates, slit: 30.76, attenuator: 104 (somehow same setting as Pb gave the same T1 rates.....??)
Carbon 1%
- T1 rates 100k: slit (30.76) and att (106)
