Superconducting wire connector and method of connecting superconducting wires

A superconducting wire connector comprising:

• a plurality of superconducting wires;
• a container;
• and
• a sintered body containing MgB2, the sintered body being disposed inside the container,
• wherein the superconducting wires are connected by the sintered body,
• wherein at least one of the superconducting wires includes a superconducting core having a first outer surface,
• wherein a stabilizing material is disposed on an inner periphery of the superconducting core, and a metal sheath covers an outer periphery of the superconducting core,
• wherein the sintered body is in contact with the first outer surface of the superconducting core,
• wherein at least one of the super conducting wires is disposed through the container,
• wherein the metal sheath has an opening at an intermediate portion of the superconducting wire in a longitudinal direction so that the outer peripheral surface of the superconducting wire core is exposed, and
• wherein the intermediate portion at which the superconducting wire core is exposed is inside the container, and an end surface of the superconducting wire is outside the container.
