Title: Microfabricated, 94 GHz, 25 W, Helical Traveling Wave Tube
Agency: NASA
Contract: NNX12CA45C
Award Amount: $749,944.00
 

Abstract:

Teraphysics Corporation completed the Phase I objectives for the electrical design of a 94 GHz, 26 W TWT with 53% overall efficiency, including the helical circuit with efficiency enhancing taper, input/output couplers, electron gun, magnetic circuit and multistage depressed collector. The device includes a novel, microfabricated, helical circuit with electron beam propagating above the helix rather than through the middle. In addition to completing all of the proposed Phase I objectives, we designed vacuum windows, made significant progress on the mechanical design, fabricated the electron gun electrodes and circuit block, and conducted machining trials, and brazing experiments.The successful Phase I results at 94 GHz along with Teraphysics' proven results at 95 and 650 GHz warrant further development of the 94 GHz TWT in a Phase II program. If awarded, we will apply our relevant experience and the Phase I results to fabricate, assemble, and test a 94 GHz TWT. The advantages of implementing high efficiency TWT amplifiers into NASA spacecraft compared to the current state of the art include lower system power requirements, reduced payload volume and reduced thermal management challenges.
