We present the results of the studies aimed at developing small-size traveling-wave tubes (TWTs) with multiple sheet electron beams, which operate in the short-wavelength part of the millimeterwaverange. Two versions of such TWTs are considered. The TWT operating at frequencies near 0.22 THz with a triple sheet beam, which interacts with the higher transverse mode of the slow wave structure in the form of a dual comb, is studied. We describe the design of the electronoptical system which forms a beam consisting of several sheets with elliptical cross sections having an area compression of about 16 units. We also consider a TWT with a slow-wave structure in the form of a 3D meander line with several channels for electron beams, whichis placed in a rectangular waveguide. On each side, this structure is supported by dielectric supports. A slow-wave V-band (50–70 GHz) structure has been designed for a TWT with channels for four sheet electron beams. The results of calculating electrodynamic characteristics of the slow-wave structure are presented along with the results of three-dimensional simulation of the processes of the electron–wave interaction by the particle-in-cell method.
