Numerical simulation of electron beam relaxation in dense media

Monte Carlo calculations have been carried out for the relaxation of electron beams in dense media. Calculations have been carried out for initial beam energies from 0.2 to 1 MeV and for targets of copper, tin, and air. The results on the energy dissipation are compared for the cases in which the incident electrons have a function energy distribution and a realistic energy distribution. Comparison reveals a satisfactory agreement with data reported by Spencer. The intensity function for the volume bremsstrahlung of the electron beam is calculated.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 10, pp. 84–87, October, 1981.
