Applied Nanotech is blending next-generation carbon nanotube technology with cold cathode X-ray tubes, which were first introduced in the late 19th century, only to vanish quickly with the invention of a hot cathode called ductile tungsten in 1910. With support from JPL under a Small Business Innovation Research (SBIR) contract, Applied Nanotech was able to bring cold cathode technology back to life with the mindset to produce smaller and more energy-efficient X-ray devices, especially ideal for applications requiring minimum power within harsh environments. NASA is considering replacing the standard hot cathodes used on satellites with the carbon cold cathode technology as a source for low power electric propulsion thrusters. Applied Nanotech's collaboration with JPL has allowed the company to extend the applications of its cold cathode technology and enhance its licensing policies. For its first commercial achievement involving carbon cold cathodes, Applied Nanotech customized and sold the technology to Oxford Instruments plc-based in the United Kingdom, with American offices in Concord, Massachusetts, and Clearwater, Florida-for use in the company's Horizon600 self-contained, portable X-ray fluorescence spectrometer. The Horizon600's unique digital cold cathode X-ray tube allows for pinpoint therapy in medical fields.
