Title: Innovations of John M J Madey
Introduction
John M J Madey is a notable inventor based in Honolulu, HI (US). He has made significant contributions to the field of technology, holding a total of 3 patents. His work primarily focuses on advancements in electron guns and X-ray sources.
Latest Patents
One of his latest patents is the "Temperature Stabilized Microwave Electron Gun." This invention addresses the temperature rise caused by backstreaming electrons, which is countered by a corresponding decrease in temperature at the cathode surface. This is achieved through the conduction of heat deposited by a pulsed laser that uniformly illuminates the cathode surface just before the microwave pulse. Additionally, variations in temperature across the cathode surface can be compensated using a second laser pulse during the RF pulse, ensuring a constant thermal power input.
Another significant patent is the "High Efficiency Monochromatic X-ray Source Using an Optical Undulator." This method involves generating energetic electromagnetic radiation by injecting laser radiation into an optical cavity characterized by a round-trip transit time for that wavelength. The process includes a series of separated radiation intervals, where at least one optical macropulse generates an associated circulating optical micropulse, reinforcing the electric field amplitude during the radiation interval.
