Research on Parameter Design Method of Concentric Nested Hall Thruster

According to the future demand for high power Hall thruster at home and abroad， the research status and technical advantages of concentric nested channel Hall thrusters are discussed. The structure and magnetic circuit of a feasible nested channel Hall thruster are introduced. A method is proposed to determine the structure of the Hall thruster. The method of optimizing the parameters of the nested Hall thruster is given. The process of the nested channel is expected to be filled with the channel design and the thermal design. It will provide reference for engineering application in the future.
