Abstract

The invention discloses a magnetic screen for a low-power Hall thruster and a fixing structure. The magnetic screen comprises a magnetic screen body and a magnetic screen installation support, whereinthe magnetic screen body is made of a magnetic conductive material, and the magnetic screen installation support is made of a non-magnetic-conductive austenitic stainless steel material. The two parts are matched with each other through the boss, stable and reliable connection is achieved in a fusion welding mode, and meanwhile the two parts are connected with other parts in the thruster througha flanging structure on the magnetic screen installation support. A magnetic circuit structure similar to a high-power Hall thruster is realized through an idea of integrally designing the inner magnetic screen and the outer magnetic screen. And meanwhile, the ceramic channel can be fixed on an integrated structure of the inner magnetic screen and the outer magnetic screen, so that the differencebetween the axial length of the inner coil and the axial length of the ceramic channel in the low-power Hall thruster is made up.
