General Info

Secondary Beam(s)

  • 16m,gN7+
  • Energy: ~12 MeV/u
  • Requested rate and purity:
    • 2x105 pps, >50 %
  • Achieved rate (pps/pnA):
    • (XXX pps/pnA) [XXX pnA XXXXXX]
  • Purity:
    • XXX% best, XXX% typical

Tuning Info

Primary Beam (energy) [max pnA]

  • 15N?? [13.5 MeV/u, MeV][200 pnA]
  • Target: D2 Gas Cell cooled to 90K [1400 mb]
=========16m,gN===========

16m,gN - 37 mm D2 gas target

Beam Label Energy [MeV] Brho [Tm] calc / TOF Scale Factor DE-E (50 / 1000 um) q-Fraction Target
15N7+ primary 202.5 XXX calc XXX/XXX MeV none
15N7+ degraded XXX XXX calc 76 / 244 MeV 99% D gass
16N7+ secondary 190 1.1366 calc % 18/172 MeV 99% D gass
15N6+ contam XXX XXX calc % MeV 1% D gas
  • 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...)
