Abstract
Proceeding from the Boltzmann kinetic equation for electrons, the system of multigroup equations for the zeroth, first and second moments of the electron distribution function is derived. The system includes equations for the balance of concentration, flux density and momentum flux density of electrons, and it is intended for numerical simulations of transport and kinetics of low-energy electrons in weakly ionized cold plasmas. The results of numerical calculations of electron swarm development in a uniform electric field in neon according to the developed multigroup model are compared with the results obtained by the Monte Carlo method to demonstrate the accuracy of the proposed model.
