Максим Юрьевич Титов, Андрей Витальевич Лоян

Abstract


Paper represents results of an analysis of electric and magnetic fields distributions in the acceleration channel in stationary plasma thruster, performed to find relationships between properties of ionization and acceleration zone (IAZ) and parameters of magnetic field. There were found: connections between IAZ boundaries and maximum value of the radial component of magnetic induction Br, connections between IAZ length and magnitude of the maximum longitudinal gradient of Br. A directly proportional dependence of the electric field strength on the maximum longitudinal gradient Br was found. Deviation of lines with constant electric potential from magnetic force lines is revealed. The analysis of the relations is carried out over the entire width of the accelerating channel. Results of verification of the detected relations are given.

Keywords
