Electrical Breakdown and Tracking Characteristics of Pulsed High Voltages in Cryogenic Helium and Nitrogen
The use of superconducting energy storage systems has become of interest in the past few years as a possible solution to the large energy-storage requirements in a pulsed-type fusion reactor such as the proposed SFTR (Scyllac Fusion Test Reactor) at Los Alamos Scientific Laboratory. In these systems rather large voltage pulses are imposed on components as a result of associated electrical circuitry, which includes the superconducting energy system. It is therefore essential to know the dielectric strength of the cryogens proposed for use in the superconducting system so that the engineer can design any high-voltage components within reasonable limits of safety.
