SUPERCONDUCTING CURRENT LEAD, SUPERCONDUCTING CURRENT LEAD DEVICE, AND SUPERCONDUCTING MAGNET DEVICE

摘要

A superconducting current lead supplying current to a superconducting device includes a plurality of electrode members, a support rod that is arranged between the plurality of electrode members so as to connect the plurality of electrode members each other, and a plurality of thin multi-layer rare-earth-based superconducting wires, each of which has a tape shape and includes a main surface and both end portions being connected to each of the plurality of electrode members, and each of which is arranged on an outer surface of the support rod, wherein an angle ¸ is 40 - 60 degrees that is formed by each of the main surfaces adjacent to each other in a circumferential direction of the support rod on the outer surface of the support rod.
