Results of research and development of TWT of average power in the frequency range 16−46 GHz are presented. The design and technology of its electron-optical and spiral slow-wave systems are described. The possibility of using the spiral SWS wide-band TWT at wavelengths of up to 4 mm is analyzed. It shows the possibility of manufacturing technology for the SWS such TWT helix spiral with an inner diameter of 0.4 mm of refractory metals. It discusses the main methods to the development of technology and the results of experimental model slow-wave systems for TWT submillimetr wavelength range.
