Monte Carlo simulation of nonrelativistic electrons transport and heavy ion track formation in matter

摘要

Monte Carlo (MC) study of the transport of non-relativistic electrons in the matter is presented. The simulations were made using a new computer code TRELM (Transport of Electrons in Matter) which is recently developed by authors. This code is based on individual scattering technique which make allows one to trace each electron history taking into account both elastic scattering and electronic energy losses. The main objectives of this work are to calculate imparted energy distributions in the target and related parameters at low-energy electron beams irradiation as well as to investigate formation of the heavy ion track due to secondary delta-rays transport processes. It is found that calculated data are in reasonable agreement both with previous similar results and with recently obtained new experimental data on observations of heavy ions tracks shapes in nuclear photoemulsion near ion stop-point.
