Abstract
The research status on the high-power Hall electric propulsion technology is introduced, and the tendency is also presented on the basis of space missions in the future. According to the technical characteristics of the high-power Hall electric propulsion, several key technologies, i.e. ion thermalization and enhanced erosion due to the high plasma density, interference of the magnetic field induced by the large current, thermal design in the high power, realization of the large size components, large emission current hollow cathode, discharging with alternative propellants, internally mounted cathodes and ground test problem, are expatiated. Finally, some settlements and technical solutions are given in a situation.
