| Beam | Label | Energy [MeV] | Brho [Tm] | calc / TOF | Scale Factor | DE-E (50 / 1000 um) | q-Fraction | Target |
|---|---|---|---|---|---|---|---|---|
| 15N7+ | primary | 202.5 | 1.13738 | calc | 16/186 MeV | none | ||
| 15N7+ | degraded | 192.4 | 1.1086 | calc | 0.975 | 17/176 MeV | 99% | D gass |
| 16N7+ | secondary | 190 | 1.1366 | calc | 2.5% | 18/172 MeV | 99% | D gass |
| 15N6+ | contam | 150 | 1.1366 | calc | 21/128 MeV | 1% | D gas |
- 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...)
