General Info

Tuning Info

Primary Beam (energy) [max pnA]

  • 7Li3 [11 MeV/u, 77 MeV][100 - 150 pnA ??]
  • Target: D2 Gas w/ 1.9 mg/cm2 HAVAR windows (3.7 cm, 1400 mbarr, T=90K)

8Li3+

Beam Label Energy [MeV] Brho [Tm] calc / TOF Scale Factor [%] DE-E (50 / 1000 um) DE-E (150 / 1000) Target
7Li3+ primary 77 1.11976 calc 3.4 / 73.6 MeV 10.7 / 66.3 MeV D2
7Li3+ degraded 74.9 1.1043 calc 3.5 / 71.4 MeV 11.0 / 63.9 MeV D2
8Li3+ secondary 73 1.1647 calc 5.5% 3.9 / 69.1 MeV 12.6 / 60.4 MeV D2
  • Scale Factor:
    • [May/June 19] 8Li3+ [73 MeV] from 7Li3+ [74.9 MeV] scale factor = 1.1647/1.1043 = 1.0547 (5.5%)
  • Expected calculated rates for tuning (acceptable - ideal):
    • At EXIT Detector: >500-2000 pps/pnA (midplane slits set to ~+-4 mm, ~3% momentum acceptance).
    • At HELIOS Cross Detector: >200-500 pps/pnA (assumes ~40% transmission, maybe on the high side, need more empirical data)
