Patent Summary

A method and apparatus for enhancing the critical current and reducing AC losses of superconducting devices by locally modifying the superconducting material's critical current density. The method involves identifying regions of reduced critical current density within the device, such as inner turns of coils or filaments in striated tapes, and applying one or more of the following modifications: decreasing the cooling temperature, modifying the composition or type of superconducting material, varying the cross-sectional area of the superconducting material, or using temperature variations to enhance critical current density. The apparatus includes a system for designing and optimizing superconducting devices based on these principles.
