Description
Summary:The High Magnetic Field Laboratory developed a 45-T hybrid magnet. To test this magnet, a new pair of high-temperature superconducting current leads rated at 16 kA were developed. This paper addresses the design and test of those current leads. To minimize heat loads at the cold end, Bi-2223 high-temperature superconductors were used. The foil-type main heat exchanger is cooled by 77-K liquid nitrogen (LN2) and gas nitrogen (GN2). The busbar for International Thermonuclear Experimental Reactor, an Nb-Ti low-temperature superconducting (LTS) cable, is used to connect the magnet coil for easy access to the LTS cable. The insulation on the current lead was designed on the test target of 10 kV.
