Abstract

The invention provides a superconducting magnet which comprises a vacuum container and a refrigerator. A cold screen and a superconducting coil are arranged in the vacuum container; superconducting wires are wound on a coil framework to form the superconducting coil, and two free ends of the superconducting coil are connected with a superconducting switch by superconducting connectors to form a closed superconducting circuit; the refrigerator is arranged on the vacuum container and comprises a primary cold head and a secondary cold head, and the primary cold head is thermally connected with the cold screen; the superconducting wires are made of superconducting materials with critical superconducting transit temperatures higher than 35 K; the superconducting connectors are made of superconducting welding flux with a low melting point, can be cooled by the aid of the secondary cold head or cooling media and accordingly can be assuredly in superconducting states. Compared with low-temperature closed-loop superconducting magnets in the prior art, the superconducting magnet has the advantage of high superconducting stability.
