  • Scale Factor:
    • [June 19] 29Al13+ [307.4 MeV] from 30Si14+ [319.8 MeV] scale factor = 1.04767/1.009 = 1.038
  • Expected calculated rates for tuning (acceptable - ideal):
    • At EXIT Detector: >250-1000 pps/pnA (midplane slits set to ~+-4 mm, ~3% momentum acceptance).
    • At HELIOS Cross Detector: >70-250 pps/pnA (assumes ~25% transmission, maybe on the high side...)
