トコイルを製造する方法である。The first method is to fabricate a substrate by laminating a second metal plate made of Nb on the surface of a first metal plate made of a Cu-Sn alloy, and then perform a diffusion heat treatment on this substrate to internally release Nb and Sn. After reacting to generate an internal Nl)+Sn superconducting intermetallic compound layer, chemical methods such as electrolytic etching using strong acids such as sulfuric acid and nitric acid as an electrolyte, or mechanical methods such as electrical discharge machining and lathe machining are performed. After machining, the Nb3Sn superconducting intermetallic compound layer and the second metal plate are cut into a planar spiral shape to form a spiral groove.
*The second method is to form a Sn superconducting circuit and build a superconducting magnet coil by layering this substrate multiple times. A spiral groove is carved to reach the first metal plate to form a spiral circuit, and then a diffusion heat treatment is performed to react Nb and Sn to form a spiral Nb3Sn superconducting intermetallic compound. In this method, layers are formed to form an N b3S n superconducting circuit, and a plurality of these substrates are laminated to produce a superconducting magnet coil.

Therefore, there is no need to process grooves on the substrate, and a superconducting magnetite coil with high mechanical strength can be manufactured. In addition, by freely setting the heating beam irradiation direction, it is possible to create a current circuit with a free shape.
Not only can a smooth current circuit be manufactured, but also a superconducting magnet coil having a current circuit with a desired width can be manufactured by adjusting the irradiation width of the heating beam.

イルの製造方法。A substrate obtained by laminating a first metal plate containing at least one of two or more metal elements constituting a superconducting intermetallic compound and a second metal plate containing the remaining metal element among the metal elements. The inside of the substrate is heated to a high temperature by irradiating a heating beam from outside the substrate onto the front or back surface of the substrate so as to draw the same trajectory as the current circuit of the superconducting magnet coil to be manufactured. A compound-based superconducting magnet coil characterized in that a metal element contained in the first metal plate and a metal element contained in the second metal plate are reacted inside the substrate to form a current circuit made of a superconducting intermetallic compound. manufacturing method.
