He has made significant contributions to the field of electrical engineering, particularly in the development of crossed-field amplifiers. His innovative approach has led to advancements that improve the performance and reliability of these devices.
Latest Patents
Vaughan holds a patent for "Jitter suppression in crossed-field amplifier by use of field emitter." This invention provides a crossed-field amplifier that features an anode and a cathode, creating an electric field across a magnetic field in an interaction area. A field emitter is strategically placed within a slot on the outer surface of the cathode. This field emitter emits an electron current in response to the electric field, supplying priming electrons that enhance the startup time of the amplifier. The emitted electron current has been shown to initiate secondary emissions of electrons from the cathode, effectively reducing the irregular startup or 'jitter' commonly experienced at low pulse repetition frequencies. In an alternative embodiment, a thermionic emitting filament is positioned between adjacent anode vanes, emitting electrons that create x-rays impacting the cathode surface to initiate secondary emissions.
