Description
technical field [0001] The invention relates to the technical field of superconducting magnet system engineering in a space propulsion ground simulation environment, and mainly relates to a long-path cooling system for a low-temperature superconducting magnet system. Background technique [0002] Space propulsion technology is a new type of electric propulsion technology that uses electromagnetic force to act on charged particles to generate thrust. The generally used ion propulsion is to accelerate the ejection of ions generated by the ionization of the working fluid under the action of an electrostatic field to generate thrust. When conventional magnetic coils or permanent magnets are used to generate the required magnetic field, the volume of the magnet itself is too large, and the efficiency decreases after the central magnetic field is dissipated. performance inflection point. Therefore, superconducting magnets can be well satisfied, not only can provide higher magnet...
