Abstract

The linearized two-fluid hydrodynamic equations were used for the analysis of gradient-driven Rayleigh-type instabilities in Hall plasma thrusters. The derivation of instability conditions and a general criterian for stability of azimuthally propagating perturbations was also discussed. The typical values of the applied magnetic and electric fields calculated for a kilowatt-range Hall thruster were 200 G and 100 V/cm, respectively. The experimental results confirmed the presence of the purely azimuthal high-frequency waves inside the channel of the laboratory Hall thruster.
