description: The given work is devoted to the study of the least described physical processes in an ion thruster. The purpose of the work was an analytical description of the effects caused by the limitation of the power of the onboard power supply, a description of the processes of neutralization of the ion flow, and a description of the possibility of using computer modeling for studying neutralization processes. In the course of the work, the dependence between the thrust force and the parameters of the power supply was established. The parameters of the source providing maximum thrust are found. From the analysis of the dependence of the extreme thrust force on the parameters, the ranges of the power supply parameters corresponding to different modes of operation of the ion engine are obtained. The analysis of the energy price of thrust and efficiency allows you to choose the optimal working fluid for the thruster. An expression for the cross section of the particle annihilation process is obtained, as well as relations describing the change in the concentrations of particles with a coordinate due to neutralization. The possibilities of the CST Studio package for modeling neutralization processes are shown. For the numerical evaluation of neutralization processes, an algorithm has been developed in the Python programming language, with the help of which the dependence of the particle concentration on the coordinate, taking into account the annihilation processes, the distribution of the potential in the field of modeling, taking into account the volume charge of particles, the dependence of particle velocities and ion free path lengths on the coordinate are obtained, as well as the change in the mixed particle flow with the coordinate.
