ABSTRACT:
A superconducting pin and socket conductor is formed with a cylindrical pin of superconducting material, such as niobium, which fits into a mating superconducting cylinder, such as niobium or titanium, which is open at the top. A superconducting wire is laser welded to the bottom of the cylinder and a second niobium wire is laser welded to the top of the pin. A sleeve of a material, such as copper, aluminum, or magnesium, which at liquid helium temperatures has a much higher coefficient thermal expansion than the superconducting material, surrounds the cylinder. As a result, upon cooling the outer sleeve crimps the cylinder into a firm and uniform contact along the length of the pin.
