Short-Pulse Switches for Airborne High-Power Supplies.
Abstract
Prototypes of both magnetically and optically activated high current, high voltage switches are fabricated and tested. Feasibility is demonstrated for both the silicon optically-activated and the indium antimonide, magnetically-activated switches. A near-intrinsic silicon switch shows resistance decrease of almost four orders of magnitude with radiation from Xenon flash lamps. Resistance increase of an InSb cube is demonstrated; this result leads to theoretical predictions of three orders of magnitude resistance increase for a corbino-disk device with modest fields (1-3 wb/sq m).
