Tuning Info

Primary Beam (energy) [max pnA]

  • 15N6+ [13.5 MeV/u, MeV][150 pnA]


  • Target: D2 Gas Cell cooled to 90K [1400 mb]
=========16m,gN===========

16m,gN - 37 mm D2 gas target

  • Scale Factor:
    • [Oct 19] 16N7+ [190 MeV] from 15N7+ [192.4 MeV] scale factor = 1.1366/1.1086 = 1.025
  • Expected calculated rates for tuning (acceptable - ideal):
    • At EXIT Detector: > pps/pnA (midplane slits set to ~+-4 mm, ~3% momentum acceptance).
    • At HELIOS Cross Detector: > pps/pnA (assumes ~25% transmission, maybe on the high side...)
