Abstract

Characteristics of discharge oscillations at a frequency range of 10-100kHz in a Hall thruster were investigated using a 1kW class anode layer type Hall thruster. An oscillation model was proposed where the oscillation is due to ionization interaction between electrons and neutral particles and where the phase velocity of electrons is different from that of neutral particles. The predicted unstable operational condition agreed with the experimental results in tendency. This model shows that decrease in cross section of discharge chamber should make stable operation range extended, and experimental results supported this assumption.
