Computer Modeling of Processes of Radiation Defect Formation in Materials Irradiated with Electrons

Abstract

Computer modeling of the spectrum of primary beaten-out atoms and the concentration of point radiation defects irradiated with electrons have been performed using cascade and probabilistic method. A mathematical model of energy spectrums of primary beaten-out atoms is obtained. Algorithms of calculating the primary beaten-out atoms spectrum and concentration of radiation defects are developed. Cascade and probabilistic functions are calculated subject to the quantity of interactions and infiltration base, primary beaten-out atoms spectrum, and defect concentrations in materials irradiated with electrons. The results of calculations of the defect concentration are compared with calculations made earlier without considering energy losses. It is apparent that accounting for energy losses makes a significant contribution to the primary beaten-out atoms and to the defect concentration.
