Abstract

The pulsed magnetic fields encountered in synchrotrons, accelerators, and the proposed Tokamak fusion experiment require intermediate energy storage to reduce the large fluctuations in power demand. Only superconducting coils are expected to be economical at sizes required for reactors. The challenge of switching energy between inductors has produced many solutions, none of which is without drawbacks. This paper defines performance parameters, compares the various schemes, and proposes an ideal system with optimal response. A companion paper proposes a modified rotating coil system to approximate the optimal design.
