Краткое описание

According to theoretical and experimental research of orotrons, which are diffraction radiation oscillators with spatially developed electromagnetic systems, usually being excited by non-relativistic spatially developed electron beams, this class of devices can be successfully used in the practical applications for THz frequency range. One of the major problems to be solved when the efficiency of such sources increases with the shortening of their operation wavelength is how to ensure a high utilization factor of all partial layers of a highly perveance spatially developed electron beam in the electron-wave interaction zone. This can be achieved by increasing the microwave field strength in the energy exchange zone between electrons and electromagnetic waves. The klynotronic effect has been proven to be an efficient way of increasing the utilization factor of all partial cross-sectional layers of a spatially developed electron beam. In this study, we will discuss the mathematically simulated energy characteristics of electron-wave interaction in a radial electron flow orotron with an underlying azimuthal comb serving as a diffraction grating mounted on the useful surface of a flat mirror in a two-mirror open cavity. The results of mathematical simulation and optimization of the energy characteristics of electron-wave interaction in the klynoorotron of the terahertz range made us believe that, due to the klynotronic effect, the electronic efficiency can be increased up to 20% in oscillators of this design.
