Abstract

Abstract: With the proposed of ATON-Hall thrusters,a series of studies were carried out based on pre-ionization phenomenon in buffer. However, the selection of pre-ionization rate is still inconclusive.Therefore, two-dimensional axisymmetric full particle PIC (Fully-kinetic Particle-In-Cell) simulations were carried out based on the real size of SPT-100 Hall thruster to simulate the discharge process in the discharge chamber. The relations between and among pre Ionization rate, low frequency oscillation in the discharge channel and wall corrosion of Hall thruster were mainly studied. The simulation results show that increasing the pre-ionization rate in the buffer chamber can effectively suppress low frequency oscillation, and improve the performance of the propeller. But at the same time, the increase of the energy of ion impacting on the channel surface aggrevates the corrosion of the surface, and shorten the propeller′s shorten service life.
