Abstract
Novel configurations to improve the performance of superconducting magnetic energy storage system are described. The use of poloidal grading of the conductor, enabled by the use of 2nd generation YBCO conductors, is described. Methods to improve system performance when limited by the critical field of the superconductor are described, using optimized thin winding pack and thick winding pack toroidal geometries, where a uniform or near uniform magnetic field can be generated in a torus. Configurations that minimize structural requirements, weight and costs are also described. Cryostat innovations useful with toroidal systems are provided.
