Estimating event rates for commissioning running this fall:

Assume 10 GeV e-e beam, 10^7 gamma/GeV at endpoint

Assume plastic target of 0.2 g/cm^2 -> 0.225 cm width

Total hadronic rate: ~100 kHz


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
