Abstract
A superconducting coil assembly. The assembly includes an insulating substrate, a plurality of insulating layers disposed in a stacked assembly on the substract, and a superconducting spiral pattern between the substrate and the adjacent insulating layer and between each adjacent pair of insulating layers. Superconducting connecting portions connect the spiral patterns to form a continuous thick film superconducting coil of right hand or left hand orientation. The spiral patterns and connecting portions are thick films of a high temperature ceramic superconducting material. A superconducting connecting link may interconnect the ends of the continuous coil to form a closed loop. The insulating layers and spiral patterns may be deposited successively over an insulating substrate. Alternatively, the insulating layers may be annular disks with vias therethrough for connecting the spiral patterns. Preferably, the cross-sectional area of each coil portion varies inversely with its radius to effect a constant critical current capacity throughout each coil portion. A method for producing the coil assembly is also disclosed.
