Design, Construction and Testing of a Pulsed High Energy Inductive Superconducting Energy Storage System

Major problems associated with inductive energy storage systems operated at high repetition rates include: breaking high currents in inductive circuits; developing a low loss superconductor and from it building a coil which remains superconducting during the rapid charge period; and building a low heat leak non-conducting dewar. Theoretical analyses concerning conductor energy losses, transient heating effects, electrical circuits, and switch actuation, were conducted. To confirm these analyses experiments were conducted on model non-conducting dewars and 1 and 7 kJ stored energy model coils using a pneumatically actuated vacuum interrupter.
