Abstract

A 300-kJ superconducting inductive energy storage experiment at the Los Alamos Scientific Laboratory involves supporting a superconducting coil within a fiberglass cryostat with a secondary coil on the outside of the cryostat as shown in Fig. 1. The energy storage experiment is a model for a pulsed plasma thermonuclear fusion energy source. The experiment involves charging the primary superconducting coil with a current of 10,000 A, driving a switch section of the circuit from its superconducting state to its normal resistive state, producing a large voltage across the switch. The transient current decay in the primary loop induces a large current into the secondary coil and a resistive load connected in series.
