ABSTRACT

Three-stage slow-wave system, which allows us to provide the 94 GHz klynotron operation on hybrid surface-volume modes, is proposed to reduce the ohmic losses. Simulation results of three-stage plane gratings in 3 millimeter wave length range show the possibility of effective excitation of hybrid modes using electron beam in klynotron regime. It is shown that THz klynotron operation on hybrid surface-volume modes may substantially increase both the efficiency and the output power of the tube. The parameters of the operation of 94 GHz klynotron with the three-stage slow-wave system on hybrid surface-volume modes such as the start current value, frequency tuning range, spectral characteristics and operation mode settling time were obtained as the result of simulations.
