Kinetic model of radiation-induced gas conductivity

A kinetic equation for low-energy electrons induced in gas by ionizing radiation is studied. The kinetic equation takes into account elastic, inelastic, and ionization collisions between electrons and gas molecules, as well as the interaction with an external electric field. The process of the conduction current generation is considered. A small parameter is calculated as a ratio of the energy accumulated by an electron between collisions to the thermal energy. An approximate solution is constructed of the kinetic equation for electron concentration and flow. The study resulted in obtaining quadrature formulas for the calculation of electron conduction of an ionized gas in the model of a radiation-induced electromagnetic field.
