Cable-in-conduit superconductors are composed of a cable of many fine composite strands encased in a strong, protective jacket, with helium coolant filling the interstices of the cable. Because of the high degree of subdivision of the composite and its consequent large cooled surface, such conductors are capable of stable operation at quite high current densities. The designer of such conductors is frequently given the field at the conductor and the overall current density and asked to specify the remaining variables of the conductor (e.g., the strand diameter, the hydraulic path length, the void fraction of the cable, and the Cu/SC ratio). This paper outlines a rational procedure for determining the most problematic variables, the two composition variables that determine the proportions of copper, superconductor, and helium in the cable space. All other variables of the conductor are assumed known. 14 refs., 8 figs.
