Abstract
A low current, ultra-low heat-leak multi-line DC cable is being developed using the high Tc superconductor YBCO for the purposes of delivering 10s of milliamperes of current from a current source at room temperature to superconducting electronic circuitry operating at about 4 degrees Kelvin. The cable's very low dissipative losses and thermal conductance mean that the 4K stage of a supporting cryocooler platform will suffer a significantly lower heat load, so reducing the size, weight and power consumption of the system. A target performance is for a heat-leak of less than 1 mW per Amp of current given that the cable links a temperature station at 60K to one at 4K.
