Commissioning Event Rates
From GlueXWiki
Estimating event rates for commissioning running this fall:
Assume 10 GeV e- beam on incoherent radiator, 10^7 gamma/GeV at endpoint
Assume plastic target of 0.2 g/cm^2 -> 0.225 cm thickness
Generate events with E(gamma) = 0.15 - 9.99 GeV
Total hadronic rate: ~100 kHz (prelim.)
| Photon Range (GeV) | Photon Flux (%) | Event Rate (%) |
|---|---|---|
| 0.15-1 | 51.1 | 64.2 |
| 1-2 | 17.0 | 14.8 |
| 2-3 | 9.07 | 6.49 |
| 3-4 | 5.95 | 3.96 |
| 4-5 | 4.33 | 2.75 |
| 5-6 | 3.37 | 2.10 |
| 6-7 | 2.77 | 1.71 |
| 7-8 | 2.38 | 1.47 |
| 8-9 | 2.13 | 1.31 |
| 9-9.99 | 1.95 | 1.20 |
