Abstract

The invention relates to a single-coil magnetic shielding low-power Hall thruster which comprises an inner magnetic conductive column, an inner magnetic pole, a magnet exciting coil, an inner ceramic discharge channel, an outer ceramic discharge channel, an outer magnetic pole, an outer magnetic conductive column, an anode and a magnetic conductive bottom plate. Heat consumption generated by eddy current in a magnetic circuit is reduced by adopting a single-turn coil winding, and the magnetic field of the magnetic circuit is adjustable; the magnetic flux required by the low-power thruster can be processed, heat consumption which is continuously increased in the magnet exciting coil can be reduced to the maximum extent, and the thruster is small in size and has the advantages of being good in heat dissipation, compact in structure, high in performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of Hall thrusters, in particular to a single-coil magnetically shielded low-power Hall thruster. Background technique [0002] Hall thruster is currently a typical electric propulsion device in the world. The main structure of Hall thruster includes: cathode assembly, anode assembly, magnetic circuit assembly, gas circuit assembly and installation assembly. The smaller the power of the thruster, the larger the area / volume ratio of the corresponding discharge channel, which means that more charged particles will be deposited on the wall of the channel, resulting in energy loss and reducing the performance of the thruster, and at the same time causing the thermal effect of the thruster. Therefore, compared with mature kilowatt-level power thrusters, the performance decline of low-power Hall thrusters is more obvious. [0003] In order to improve the performance, various structures of Hall thrusters have been ...
