Abstract:

Thin targets of low atomic number were assumed to be bombarded with 25-Mev electrons, 600-kv X rays and prompt fission gamma radiation. The resulting high-energy secondary electrons were calculated theoretically on a high-speed digital computer with respect to their intensity, energy losses, energy spectra and angle of emission spectra. The results show that 25-Mev electrons, 600-kv X rays and prompt fission gamma radiation produce a maximum efficiency of high-energy secondary-electron emission of 8.0, 0.05, and 0.3 percent, respectively. Experimental results from 25-Mev electron irradiations agree very closely with these theoretical numbers. An experiment is planned for the 600-kv X-ray radiation source.
