SUPERCONDUCTING JOINT METHOD OF HTS 1G WIRE WITH SUPERCONDUCTING POWDER USING MELTING DIFFUSION TECHNIQUE

摘要

Provided is a superconducting joining method of first generation superconducting wire, including: removing normal conductor parts from joining portions of first generation superconducting wires to be joined to each other, thereby exposing superconducting filaments; after inserting a superconductor powder into the joining portions, bring the superconducting filaments of the first generation superconducting wires to be joined to each other into contact with each other, and applying a pressure thereon; and causing the first generation superconducting wires that are brought into contact with each other to be subjected to melting diffusion and joined to each other, thereby minimizing a reduction in critical current and joining resistance.
