Structural Design of Superconducting Energy Storage Solenoidal Magnets

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 43)

Abstract

Mid- and large scale commercial superconducting magnetic energy storage (SMES) magnets have been actively studied recently. It has been found that cost is a major consideration in determining the magnet overall dimensions if the energy requirement is defined. Generally, conductor length has been considered as a critical parameter. Studies have shown that many other design requirements could be as expensive as the conductor length. This paper discusses the stress characteristics and some structural limitations for low aspect ratio solenoids. Literature and analytical relations are reviewed. Stress distributions relative to major dimensional parameters are presented. Other critical structural considerations, such as turn-to-turn contact, composite conductor configuration, are investigated.
