Computer modeling of processes of radiation defection formation in aluminum irradiated by ions

Abstract

The article considers the process of interaction of ions with aluminum and the formation of the radiation defects. The selection of an approximate expression for the interaction cross section is found and the approximation coefficients are found. Algorithms of calculation of a cascade probability function, range of the primary beaten-out atoms, concentration of radiation defects are given. Calculations of cascade probability functions depending on number of interactions and a depth of penetration of particles, ranges of the primary beaten-out atoms (PKA), concentration of radiation defects are made. Regularities of behavior and finding of area of result when calculating cascade probability functions depending on number of interactions and a depth of penetration of particles , concentration of radiation defects for the aluminum irradiated with ions are received. It is necessary to consider various factors: types of flying particles (charged and uncharged, light and Heavy), a real "physical" picture; i.e. processes occurring at interaction of particles with a substance.
