SUPERCONDUCTING WIRE MATERIAL, SUPERCONDUCTING WIRE MATERIAL CONNECTION STRUCTURE, SUPERCONDUCTING WIRE MATERIAL CONNECTION METHOD, AND TERMINAL TREATMENT METHOD OF SUPERCONDUCTING WIRE MATERIAL

摘要

A superconducting wire material connection structure is adopted in which a recessed portion formed by removing the superconducting layer (3) at the terminal (10a) of the superconducting wire material is filled with a filling material (9), and, in a section where the terminals (10a) of the first superconducting wire material (11) and the superconducting wire material (12) are arranged opposite of each other, a third superconducting wire material (13) spans and connects the first superconducting wire material (11) and the second superconducting wire material (12) along the longitudinal direction of the first superconducting wire material (11) and the second superconducting wire material (12). Thereby, it is possible to prevent peeling and damage of the superconducting layer (3) at the terminal (10a) of the superconducting wire material, and troublesome decreases in semiconductor performance in the connection portion of the superconductor wire material are avoided.
