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)
