N2 - Abstract: The work is devoted to the study of a high-pressure short-arc xenon discharge, namely, its modeling taking into account the evaporation of thorium into the discharge volume with a different shape of the working surface of electrodes. The reason for the presence of thorium atoms in the discharge plasma is tungsten cathodes doped with thorium, which are used in high and ultrahigh pressure xenon arc light sources. The strong influence of thorium atoms and the shape of the electrode surface on the electrokinetic characteristics of plasma is shown, manifested in changes in the composition and spatial distribution of plasma particles, in particular, xenon and thorium ions, which also significantly affects the generation of optical radiation. The presented results allow us to obtain radiation mainly in the ultraviolet, visible and/or infra-red regions of the spectrum.
