A kind of design method of structure for enhancing magnetic focusing type hall thruster ion beam focusing and the structure

The design method of a kind of structure for enhancing magnetic focusing type hall thruster ion beam focusing and the structure is related to space flight electric propulsion hall thruster beam focus control field, in order to solve the problems, such as that focused ion beam can be destroyed by outfield.Magnetic field is constructed in the outfield of hall thruster, the magnetic interface in the magnetic field that the magnetic field in outfield and hall thruster Inside coil are formed is straight barrel type, and cathode aperture is located at interior magnetic mirror area.Energy operative constraint of the present invention lives passive plasma body beam radially, thus the effect that enhanced beam focuses.
