The current lead of a superconducting magnet (SCM) is a conductor that connects the superconducting coils to an external power supply. Since the copper alloy generally used for such leads acts as a route for heat leak to the inside of the SCM, the authors developed a high-temperature superconductor (HTS) current lead and evaluated its properties using a measuring system for the HTS current lead. The properties of this lead enable a reduction in length, and the removal of the evaporated helium gas cooling mechanism of the current lead. The advantages of this HTS current lead enable a higher level of SCM performance.
