TERMINAL STRUCTURE OF TAPE-LIKE SUPERCONDUCTING WIRE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a terminal structure of a tape-like superconducting wire material which connects a superconducting tape with a metal terminal achieving low loss and good reliability.SOLUTION: A first surface of a superconducting tape 100 is connected with a metal terminal 200 by a first metal tape 110. A second surface of the superconducting tape 100 is connected with the metal terminal 200 by a second metal tape 120. The first surface of the superconducting tape 110 is joined to the first metal tape 110 by solder 111, and the second surface of the superconducting tape 110 is joined to the second metal tape 120 by solder 121. Further, the first metal tape 110 is joined to the metal electrode 200 by solder 112, and the second metal tape 120 is joined to the metal electrode 200 by solder 122. The structure reduces connection resistance caused by soldering and reduces loss caused by solder connection.
