Embodiment Construction
[0027] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0029] Such as Figure 1-Figure 3 As shown, a permanent magnet Hall thruster external magnetic pole structure that changes the distribution of the cathode magnetic field includes an external magnetic pole 1, an extended external magnetic pole 2, an additional permanent magnet that changes the magnetic field at the position of the cathode and moves the magnetic interface outward, and an additional permanent magnet. The magnet cover plate, the expanded outer magnetic pole 2 is fixedly arranged on one side of the outer magnetic pole 1, the expanded outer magnetic pole 2 is provided with a cathode hole 5, the size of the cathode hole 5 is larger than the diameter of the cathode, and the addi...
