Abstract

The paper describes the physical basis of the mathematical model of radiation-ion damage in solid matter. The following stages of defect generation are considered: primary knocked out atoms, atomic collision cascades (dynamic stage of damage formation) based on 6 types of cascade functions. The software implementation of the described model is included in the RTS&T code designed for statistical modeling of multi-particle (200 types of particles, resonances and ions) radiation transport in heterogeneous 3D geometries in the energy range up to 20 TeV. In the region of low energies, the RTS&T transfer model is based on direct use of all the information contained in the evaluated nuclear data files submitted in the ENDF-6 format. The report compares the results of numerical modeling with experimental data.
