The thermal spike model to estimate the parameters of latent tracks in TiO 2

Abstract

This work is devoted to the study of the radiation effects of fast heavy ions in the substance. The process of formation of latent tracks in TiO 2 as a result of irradiation with ions 132Xe with energy of 220 MeV at different temperatures
is considered in the framework of the thermal peak model. In the course of this work, a theoretical assessment of the threshold of formation and size of latent tracks depending on the irradiation temperature was made. The calculation results are compared with experimental data obtained by transmission electron microscopy. The comparison and discussion of the applicability of analytical and inelastic thermal peak models to describe the formation of latent tracks is given.
