Abstract
The performance characteristics of a cylindrical Hall thruster depending on the magnetic field near the anode were investigated. The magnetic shielding rings were designed to adjust the magnetic field near the anode in different levels. The experiment results show that decreasing the magnetic field near the anode contributes to the enhancement of propellant utilization and the narrowing of ion energy distribution. It is suggested that the ionization region extends towards the anode, meanwhile, the angular distribution of ion beam is narrower, which could be attributed to the growing azimuthal current. As a result, the thrust and efficiency are enhanced significantly. This work can provide some optimal design ideas of the magnetic field to improve the performance of the thruster.
