Abstract

The invention discloses a high-temperature superconductive magnet system for a magnetically confined plasma propeller, which comprises two magnetic mirror units in the same structure, wherein each magnetic mirror unit comprises a Dewar barrel and two high-temperature superconductive magnets; and a refrigerator is used for cooling the two high-temperature superconductive magnets in each magnetic mirror unit. mode by a conductive cooling mode and uses the refrigerator to cool the two superconductive magnets in a conductive manner, so that the high-temperature superconductive magnet system for the magnetically confined plasma propeller greatly simplifies the structure, realizes high vacuum, reduces dependence on liquid nitrogen and high-cost operations, avoids a large-size low-temperature system and equipment used in the low-temperature liquid cooling mode, eliminates risks caused by the evaporation of a low-temperature liquid, cools the magnet to a temperature below 77 K and realizes a high field by increasing the critical current of the magnets, thus a superconductive low-temperature system is compact, efficient, safe and convenient, and is beneficial for integrating a superconductive apparatus with a low-temperature device.

Description

Technical field: [0001] The invention relates to a system device for providing a magnetic field, which belongs to the field of cryogenic engineering and superconducting applications. It is a high-temperature superconducting magnet system for a magnetically confined plasma thruster. It uses conduction cooling high-temperature superconducting magnets to provide a magnetic field and promote magnetically confined plasma. Research on body propulsion. Background technique: [0002] At present, although chemical rockets will still be an excellent tool for entering orbit from the ground, their payloads are too large to be suitable for deep space exploration. With the continuous exploration of human beings in deep space, the development of new rockets has become inevitable. Electric propulsion, one of the new rocket propulsion technologies, has high specific impulse and small load, and is suitable for space propulsion tasks. At present, the specific impulse of the liquid hydrogen a...
