Abstract

In this work, results of development of a W-band O-type traveling-wave tube with sheet electron beam are presented. The staggered double-grating slow-wave stricture with wideband input/output coupling structures was designed and optimized and its high-frequency electromagnetic parameters were calculated. The results of 3D particle-in-cell simulation of beam-wave interaction in the TWT are presented. Gain over 30 dB in the 25-GHz frequency band was obtained. A sample of an electron gun with an impregnated cathode, focusing electrode, and anode, providing the formation of a sheet electron beam with a high-aspect ratio and a current of 0.1 A, was designed and fabricated. The design of the vacuum window is presented, and the technology of its fabrication is discussed.
