2015 R&D 100 Award winner

IBIS™ Photoconductive Semiconductor Switch

From our research and development efforts, our scientists have created a compact gallium arsenide-based switch capable of handling ultrahigh voltages (over 75,000 V) and current densities in less than a billionth of a second, with ultralow jitter.

Applications that require rapid application of high voltages will benefit from this technology breakthrough. The initial application for IBIS™ PCSS enable a portable capability for future nuclear weapon effects evaluations to ensure sufficiently hardened equipment.
