Compact Megavolt Switch Utilizing Novel Switching Mediums Navy STTR FY2014.A Sol No.: Navy STTR FY2014.A Topic No.: N14A-T018 Topic Title: Compact Megavolt Switch Utilizing Novel Switching Mediums Proposal No.: N14A-018-0348 Firm: RadiaBeam Technologies, LLC 1717 Stewart Street Santa Monica, California 90404 Contact: Alexei Smirnov Phone: (310) 822-5845 Web Site: www.radiabeam.com Abstract: A rugged, laser-free design of electrically controlled MV-class, ns-sub-ns switch is proposed to develop in Phase I. The novel switch design is based on combination of Drift Step Recovery Diode, and inverse-switchable dynistor used as a closing circuit and correspondingly matched charging/discharging resonant pulsed circuitry. The approach is capable of generating of fraction of MV pulses at up to kHz rep rates and GW level of peak power. Benefits: The switch can be applied for direct energy applications as a source for active denial weapon aimed to destroy enemy's electronics. It can be applied in geology and construction industry for defrosting soils, in mining for pre-processing, e.g., copper ores, and to destroy old concrete constructions for precise demolition. It can be used for replacement of vacuum tubes and gas-filled switches for wideband high-resolution radars, for pumping of frontier lasers and high power electro-optics. The switch can be applied for compact linear accelerators of ions and electrons, and pulsed-DC-RF Electron -Guns. HV Pulses shorter are essential for the studies of biological cell response to high electric fields. The proposed source substantially simplifies the generator and results in low cost and very small footprint. Other applications include high-frequency industrial plasmatrons, physical chemistry (e.g., pulsed radiolysis), and high-power radio transmitting radio navigation. Return
