Comparison of radiation damage between FLUKA and Geant
From GlueXWiki
- Photon energy spectrum used in the simulations (photon flux corresponds to high-luminosity run)
- Silicon damage function used by FLUKA
- Particle spectra 75 cm downstream from SiPM - RADCON GEANT
- Particle spectra in SiPM - FLUKA
- 1-MeV neutron equivalent (Si) fluences
- 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 | 1.01 ± 0.19 | 0.19 ± 0.03 |
- GEANT simulations estimated neutron fluence (1-MeV neutron equivalent in Si) of 30.5 n/cm^2/sec 75 cm downstream from SiPM. FLUKA simulations estimated 16.9 n/cm^-2/sec in the same location.
