Simulations
Selenium Irradiation Setup for MCNP simulations:
Flux
MCNP results for photon flux through the samples (electron beam energy is 21 MeV, energy bins are 100 keV, selenium density is 4.2 g/cc, selenium sample is cylindrical, 2 cm in diameter, 2 cm in height):
Cross-sections for various reactions (adopted from TALYS):
Production rate (1/sec) in 1 gram of natural Se (or natural Ni) assuming 22 MeV 1 microA current
