The current lead of superconducting magnet (SCM) is a conductor to connect superconducting coil to external power supply. Since the copper alloy usually applied to the current lead, acts as a route of heat leak to the inside of the SCM, we developed high temperature superconductors (HTS) current lead, and estimated the properties by a measuring system for HTS current lead. The properties of the HTS current lead enable the length of the current lead to be shortened, and the cooling mechanism of the current lead using evaporated helium gas to the removed. Such advantages of HTS current lead can realize further performances to the SCM.
