The comparison of single- and multi-solenoidal windings for superconducting storage device performance

The author compares a scheme utilizing multisolenoidal windings (MSW) in a superconducting storage device to the traditional single solenoidal winding (SSW). It has been found that in the case of a MSW assembled from a number of solenoids smaller in diameter than those used in the SSW with the same storage capacity, the stored energy per unit volume is higher than in the SSW. It is shown that there is a parameter space where MSW is preferable to SSW. This scheme also offers additional advantages such as higher reliability, controllability and durability.<>
