Embodiment Construction
[0024] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:
[0025] Please refer to the attached Figure 1-3 , a plume corrosion prevention device for a superconducting magnetic plasma thruster provided by the present invention comprises a superconducting magnet 1 located in a vacuum chamber 6, a thruster 2, a protective casing 3, a deflector 4 and Settling unit 5; Wherein, the front end of vacuum chamber 6 is provided with hatch, and propeller is positioned at the bottom of vacuum chamber 61, is generally arranged on the rear side bulkhead of vacuum chamber 1 meter. It is worth noting that the ion beam is ejected horizontally from the inside of the vacuum chamber, therefore, the hatch 61 is arranged at the front end of the vacuum chamber 6 in the horizontal direction, and the direction in which the propeller ejects the ion beam is also horizontally ejected through the hatch. The superconducting magnet includes ...
