Therefore a statistical analysis is fundamental for a reliable design. In this abstract, it is proposed a study on a Corrugated Waveguide Slow-Wave Structure for Traveling Wave Tubes in the THz region. An analytical model is validated by three dimensional electromagnetic softwares, both

Two parallel corrugations that are enclosed in a rectangular waveguide create a beam channel that supports an interaction with a cylindrical electron beam. A notable advantage of the double-corrugated rectangular waveguide slow-wave structure (SWS) is the extension of well-established cylindrical beam technology to corrugated waveguide SWSs. The structure

In contrast to the conventional klystron approach, where the distance between the cavities placed along the drift tube is a function of the plasma frequency wavelength, the new configuration exploits the interaction property of a sequence of numerous cavities allocated at fixed short distance along the drift tube. The remarkable advantage is to obtain good performance by the use of cavities with low $R/Q$ , as in the case of high-frequency and high-order mode operation. A frequency operation up to 136 GHz with 20-dB gain and an output power up to a few tens of watts are demonstrated. The promising performance of the periodically allocated reentrant cavity klystron makes it attractive for millimeter-wave applications.
