Abstract
Experiment-based computational technique for evaluation of parameters of a stationary beam plasma such as the volume average concentration of free electrons and the degree of ionization of the gas component is proposed. The power of an electron beam along with the mean free path of electrons are found from the measurements of the current-voltage characteristic and energy efficiency of the electron-beam generators. The degree of ionization of the gas mixture is calculated assuming a balance between the ionization and recombination processes of the charged particles. It is demonstrated that the dissociative recombination of particles plays the key role in plasma created by an electron beam in a gas mixture of medium pressure. The validity of the initial assumptions is estimated. Plasma characteristics in a gas mixture containing 20.9% of O2, 78.1% of N2, and 1% of H2O at pressure ranging from 1 to 2.5 kPa are calculated based on the measured current-voltage characteristics.
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.
