Abstract

The invention discloses a low-temperature and high-temperature superconductor mixed magnet for a high ambient field. The low-temperature and high-temperature superconductor mixed magnet for the high ambient field comprises an inner high-temperature superconductor magnet subassembly and an outer low-temperature superconductor subassembly; and after being respectively machined and formed independently, the inner high-temperature superconductor magnet subassembly and the outer low-temperature superconductor subassembly are welded in a nested manner to form a whole structure. On the premise that a superconductor magnet system can normally work, a superconductor safely runs under the high ambient field, the highest running current of the superconductor magnet is increased, and the running performance of the superconductor magnet is further improved. Moreover, a low-temperature superconductor magnet is arranged on the outside of a mixed magnet coil, so that the processing and manufacturing cost of the magnet coil can be effectively reduced.

Description

technical field [0001] The present invention relates to the field of superconducting magnets, and mainly relates to the design of hybrid superconducting magnet coils for high background fields. Specifically, high-temperature superconducting magnet conductors and low-temperature superconducting magnet conductors are used to process and manufacture hybrid nested magnets to solve the problem of superconducting magnet coils. Problems with quenching under conditions of high background magnetic field strength. Background technique [0002] High background magnetic field strength is the main technical bottleneck restricting the development of large superconducting magnet coils. With the development of large-scale superconducting magnet devices such as magnetic confinement fusion devices and high-energy physics devices, the realization of superconducting magnet coils providing high magnetic field strength in a limited assembly space has brought great constraints to the critical fiel...
