Abstract
PHOTOCONDUCTIVE SEMICONDUCTOR SWITCHES (PCSSS) PRESENTLY HAVE THE GREATEST POTENTIAL FOR DRAMATIC PERFORMANCE ENHANCEMENTS FOR HIGH POWER PULSED APPLICATIONS. HOWEVER, SURFACE FLASHOVER SEVERELY LIMITS THE MAXIMUM VOLTAGE THEY CAN STAND OFF IN THE OPEN STATE. APPLICATION OF A PROPRIETARY TECHNIQUE TO PCSS CAN OVERCOME THIS LIMITATION. THE TECHNIQUE HAS THE POTENTIAL TO INCREASE BREAKDOWN LASER TRIGGER POWER REQUIREMENTS BY A FACTOR OF 25. THE PROPRIETARY TECHNIQUE HAS DEMONSTRATED FIVEFOLD IMPROVEMENT OVER CONVENTIONAL VACUUM INSULATORS FOR PULSED POWER APPLICATIONS. IN PHASE I CONCEPT FEASIBILITY WILL BE STUDIED BY MEASURING THE IMPROVEMENT IN PCSS "DARK" STANDOFFVOLTAGE IN A HIGH VOLTAGE BREAKDOWN TEST FACILITY.
