Abstract

Based on the mechanism of pulsed electric discharge expansion in dense gas (at atmospheric pressure and above), an equation for the discharge channel radius was derived from the discharge energy balance, taking into account expenditures for ionization of gas involved in the discharge, Joule heating of plasma, and the discharge work against the ambient gas pressure. For the initial stage of the development of such discharge, a solution to this equation was obtained, which is in agreement with experimental data within the measurement error.
