が流れる永久電流モードとなる。The multi-core composite superconductor C manufactured as described above is used by being incorporated in a circuit similar to the circuit shown in FIG. 5, for example. Then, the copper pipe 21 and the base material pipe 25 are energized by the external power source 3 to generate heat in the copper pipe 21 and the base material pipe 25 whose resistance has been increased due to the diffusion of Ni, and the multi-core composite superconductor C is formed. Set to normal conduction state. As a result, the multi-core composite superconductor C is brought into a high resistance state, so that of the superconducting magnet 1 and the multi-core composite superconductor C connected in parallel, the power source 3 is mainly connected to the superconducting magnet 1 side where no electric resistance occurs. The current will start to flow. Then, when a predetermined current flows through the superconducting magnet 1, the copper tube 21 and the base material pipe 25 are de-energized to eliminate the heat generation and cool the multi-core composite superconductor 20. Since many Nb-Ti superconducting wires 20 inside the body C are in a superconducting state, the superconducting magnet 1 can be used even if the power supply 3 is stopped.
It becomes a permanent current mode in which a persistent current flows between the superconducting wire 20 of the multi-core composite superconductor C.

導線を得る方法である。By the way, in the above examples, the present invention was applied to the production of a high-resistance matrix multi-core composite superconductor using Nb-Ti-based superconducting wires, but the present invention is an alloy-based superconducting element wire other than Nb-Ti-based superconducting wires. It is needless to say that it can be applied to the production of a high-resistance matrix multi-core composite superconductor using Nd, or to the production of a high-resistance matrix multi-core composite superconductor using a compound-based superconducting element wire such as Nb 3 Sn . Here, in the case of producing a compound-based high resistance matrix multi-core composite superconductor,
A composite superconducting element wire with a high workability is prepared by combining two or more elements that make up the superconducting material in a state where it is not yet a superconducting material, and a large number of these are assembled and stored inside the base metal pipe. In order to manufacture a compound-based high-resistance matrix multi-core composite superconductor, it is necessary to reduce the diameter, and then to perform a diffusion heat treatment to produce a compound-based superconducting substance to manufacture a multi-core composite superconductor. When the present invention is applied, the heat treatment for producing the superconducting substance can be used for diffusion of the plating layer. Also, Nb
As another method for producing a compound-based superconducting wire such as 3 Sn-based material, a known in-situ method can be applied to the present invention. The in-situ method is that Nb and Cu are simultaneously melted, cast in an ingot shape, and then subjected to a diameter reduction process, and Nb precipitated as a resinous crystal in the copper matrix is processed into a filament shape by a diameter reduction process. A wire is formed, a Sn plating layer is formed on the outer periphery of the wire to form a strand, and then heat treatment is performed to generate Nb 3 Sn filaments in a dispersed state in a copper matrix to obtain a superconducting wire. is there.

る。"Effects of the Invention" As described above, the present invention is to collect a large number of plated composite superconducting element edges on which a plating layer made of a non-magnetic high resistance metal material is formed, and then reduce the diameter, Since it diffuses a high resistance metal element, it can be used for a permanent current switch to obtain a suitable superconductor. Therefore, by energizing the highly resistant stabilized base material and the base material pipe to generate heat, and putting the multicore composite superconductor in the normal conducting state, the entire multicore composite superconductor is brought into a high resistance state. Therefore, of the superconducting magnet and the multi-core composite superconductor connected in parallel, the current from the power source can be mainly passed to the superconducting magnet side where no electric resistance is generated. And
When a predetermined current flows through the supercurrent magnet, the stabilization base material and the base material pipe are de-energized to eliminate the heat generation and cool the multi-core composite superconductor. Since a large number of superconducting wires can be put into a superconducting state, there is a feature that even when the power supply from the power source is stopped, a persistent current mode operation in which a persistent current flows between the superconducting magnet and the multi-core composite superconductor can be performed. In addition, since the plated composite element wire is rich in workability, the number of times of the intermediate annealing treatment can be reduced, and the manufacturing cost can be reduced.
