29Al
| Beam | Label | Energy [MeV] | Brho [Tm] | calc / TOF | Scale Factor | DE-E (50 / 1000 um) | DE-E (150 / 1000) | Target |
|---|---|---|---|---|---|---|---|---|
| 30Si??+ | primary | 345 | XXX | TOF | XXX / XXX MeV | XXX / XXX MeV | none | |
| 30Si??+ | degraded | 345 | XXX | TOF | XXX / XXX MeV | XXX / XXX MeV | 4 mg/cm2 Be | |
| 29Al13+ | secondary | 307.4 | 1.04767 | calc | 66 / 241 MeV | 256 / 51 MeV | 4 mg/cm2 Be |
- Scale Factor:
- [Date 19] 12B5+ [86.8 MeV] from 11B5+ [89 MeV] scale factor = 0.9316/0.90318 = 0.0314
- Expected calculated rates for tuning (acceptable - ideal):
- At EXIT Detector: >12000-14000 pps/pnA (midplane slits set to ~+-4 mm, ~3% momentum acceptance).
- At HELIOS Cross Detector: >5000-6000 pps/pnA (assumes ~40% transmission, maybe on the high side...)
