Thermal-spikes temperature measurement in pure metals under argon ion irradiation (E = 5-15 keV)

A method for determining the parameters of energy release in dense cascades of atomic displacements and for estimating the temperature and the level of pressures in thermalized cascade regions (thermal spikes) is proposed. It is based on the measurement and analysis of the spectral composition of the surface glow of condensed media in the course of irradiation with Ar+ 5-15 keV accelerated ions, under the assumption of the presence of a thermal component of glow defined by the presence of thermalized cascade regions.
