Carbon hole target (spot++)

  • BPMs for the c-hole target center:
4A (0.5, -3.0)
4E (0.5, -3.0)

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)
