Abstract

The invention provides a Nb3Sn superconducting magnet with quench protection and a manufacturing method thereof. The superconducting magnet comprises a magnet framework, a Nb3Sn superconducting magnet, a first heater, a second heater, an insulation heat conduction layer, an insulation heat insulation layer, a heater tool and a binding layer. The second heater is arranged on one side of the Ni3Sn superconducting magnet, the thickness of the insulation heat conduction layer can be thinner, the insulation performance is reliable, and the safety performance is high. The second heater is arranged on one side of the heater tool and is large in thickness, heat of the heater can be limited to one side of the Ni3Sn superconducting magnet through arrangement of the insulating layer, and outward loss of the heat is reduced. By adopting the quench protection mode, the heat propagation path of the second heater and the diameter of the superconducting magnet is short and is only the thickness of the micron-sized insulating heat conduction film, the heat transfer efficiency is improved to the greatest extent, and the quench protection mode has important significance in improving the quench propagation speed and timely conducting heat for the instantaneous quench niobium-tin superconducting magnet.

Description

technical field [0001] The invention belongs to the field of superconducting magnets, and in particular relates to a niobium-three-tin superconducting magnet with quench protection and a manufacturing method thereof. Background technique [0002] Superconductors have three basic critical parameters, including critical temperature, critical magnetic field and critical current. The critical temperature refers to the sudden disappearance of the resistance of a superconductor as the temperature decreases, and the temperature at this time corresponds to the critical temperature point of the superconductor. The critical magnetic field is the value of the magnetic field at which a superconductor changes from a superconducting state to a normal state as the magnetic field strength increases. The critical current means that the carrying current of a superconductor has an upper limit value. When the upper limit value is exceeded, the superconductor will change from a superconducting ...
