Abstract
Proceeding from the Boltzmann kinetic equation for electrons, the system of multigroup equations for the zero and first moments of the distribution function of low-energy electrons is derived within the Lorentz approximation. The system includes the balance equations for concentration and flux density of electrons and is intended for numerical simulation of the transport and kinetics of electrons in the energy range from zero to several tens of electron volt where the angular distribution of electrons is weakly anisotropic. Results of the numerical calculations of electron transport in helium in homogeneous and inhomogeneous electric fields according to the developed multigroup model are compared with results obtained by the Monte Carlo method.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
