Microfabricated, 94 GHz, 25 W, Helical Traveling Wave Tube

Teraphysics Corporation proposes to design and develop a microfabricated, 94 GHz, 25 W traveling wave tube (TWT) with 53% efficiency for NASA applications. In Phase I, we plan to prove feasibility by completing electrical designs of all major components. In Phase II, we would complete the mechanical design, fabrication, assembly, and test of a laboratory model. To successfully complete this program, Teraphysics will apply our expertise in vacuum electronics focusing in mm-wave and THz devices; expertise in high level, three-dimensional, computational modeling; novel, patent protected, helical TWT designs for mm-wave and THz operation; and novel, patent protected, helical TWT microfabrication techniques. In Phase I, the technology will advance from TRL 2 to 3.
