- Photon energy spectrum used in the simulations (photon flux corresponds to high-luminosity run)
- Silicon damage function used by FLUKA
- Particle spectra through the SiPM
- Particle fluences around barrel calorimeter (1-MeV neutron equivalent in Si)
- Total fluence (1-MeV neutron equivalent in Si) in Si PM plane
- Particle fluences (1-MeV neutron equivalent in Si) in Hall D
- Particles per cm^2 per second in terms of 1-MeV neutron equivalent in Si estimated with FLUKA simulation (Photon beam power at target = .704 W)
| Total | Neutrons | Protons | Pions | Electrons | Positrons |
| 22.91 ± 0.18 | 18.04 ± 0.12 | 1.72 ± 0.03 | 1.80 ± 0.01 | 1.0 ± 0.2 | 0.19 ± 0.03 |
- Neutron flux in terms of 1-MeV equivalent neutrons in Si estimated with Geant simulation: 30.5 cm^-2 sec^-1.
