Abstract: 

The results of theoretical and experimental studies of oro-trons – oscillators of diffraction radiation with spatially developed electrodynamic systems, electromagnetic oscillations in which are excited, as a rule, by nonrelativistic spatially developed electron flows, attests to the potential capabilities of this class of devices when solving problems of mastering the terahertz frequency range. One of the main problems arising when the efficiency of such oscillators increases with the length of their working wave is associated with the need 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 problem is solved by increasing the intensity of the microwave field in the energy exchange zone between electrons and electromagnetic waves. An effective way to increase the utilization factor of all partial cross-sectional layers of a spatially developed electron beam is to use the clynotronic effect. The results of mathematical modeling and optimization of the energy characteristics of electron-wave interaction in the radial orotron of the terahertz range indicate the possibility of achieving an electronic efficiency of about 20% in oscillators of this design when using the clynotronic effect.
Keywords: coefficient of use of electron flow, mathematical modeling, optimization, orotron, oscillator, terahertz range, “clynotronic effect”
