Superconducting connection structure of Nb3Sn superconducting wire rod and NbTi wire rod, method for producing same, and nuclear magnetic resonance apparatus using same

Abstract

A superconducting connection structure is provided with: a connection strip that comprises an Nb alloy strip to which an element M is added (wherein the element M is an element which increases the recovery temperature and the recrystallization temperature of Nb); an Nb3Sn superconducting wire rod that comprises an Nb3Sn superconducting core material; and an NbTi wire rod that comprises an NbTi core material. With respect to this superconducting connection structure, one end of the connection strip is connected to the Nb3Sn superconducting wire rod by having the Nb alloy strip and the Nb3Sn superconducting core material in contact with each other by the intermediary of an Nb3Sn superconducting layer; and the other end of the connection strip is connected to the NbTi wire rod by having a newly formed surface of the Nb alloy strip and a newly formed surface of the NbTi core material in contact with each other.
