Magnetic field auxiliary type radio frequency preionization type induction pulse plasma thruster

The invention relates to a magnetic field auxiliary type radio frequency pre-ionization induction pulse plasma thruster which comprises a radio frequency pre-ionization coil, a pre-ionization cavity, an acceleration stage cavity, an induction acceleration coil, a bias magnetic field coil assembly and a gas distributor. The radio frequency preionization coil is formed by winding a copper pipe and is installed outside the preionization cavity. The pre-ionization cavity and the acceleration stage cavity are made of high-temperature-resistant insulating materials and integrally form a T shape. The bias magnetic field coil assembly can generate a magnetic field with adjustable intensity, and the magnetic field is distributed in the pre-ionization cavity in parallel to the axis direction and in the acceleration stage cavity in parallel to the surface of the induction coil. The induction acceleration coil is of a double-layer planar annular structure with a plurality of spiral lines connected in parallel. According
