Calculation of High-Energy Secondary Electron Emission

Abstract
The emission of high‐energy secondary electrons from thin targets of low atomic number has been calculated. The targets are assumed to be bombarded with 25‐MeV electrons, 600‐kVp x rays, and prompt fission gamma radiation. The results give maximum efficiency of high‐energy secondary electron emission of 8% for 25‐MeV electrons, 0.30% for prompt fission gamma radiation, and 0.05% for 600‐kVp x rays.
