Abstract

The results of a theoretical study of a high power W-band extended interaction klystron with a hollow electron beam are presented. Numerical studies were carried out using the PARS computer code, taking into account the thermal spread of electron velocities at the cathode. As a result of the research and optimization of the parameters, the design of the electron-optical system and the interaction system of the 6-cavity klystron was developed, which provides a record output power of 8.6 kW for a given frequency with a gain of 56 dB, an electronic efficiency of 32\(\%\) and a full efficiency of 26\(\%\). Using the developed two-stage depressed collector with a recovery efficiency of 54\(\%\) in dynamic mode, it is possible to provide the full efficiency of the device at the level of 40\(\%\). The results of numerical calculations of the dynamics of electrons and their interaction with electromagnetic fields from the cathode to the collector in the quasi-three-dimensional approximation are presented.
