The sub-THz clinotron-multiplier

2018 IEEE International Vacuum Electronics Conference (IVEC), 2018
We outline an experimental set-up for the sub- terahertz CW clinotron (a BWO with a comb-type slow- wave structure and an inclined beam) frequency multiplier oscillator. The clinotron-multiplier operation is expected to quadruple f b ~ 146.5 GHz (2.04 mm) microwave signal, which is generated in the buncher section of the device, to obtain f c ~ 586 ...

Clinotron in the amplification mode

Journal of Communications Technology and Electronics, 2015
A self-consistent nonlinear theory for a clinotron model that takes into account static electron trajectories in the focusing magnetic field and the loss in the slow-wave structure, the clinotron amplification mode is analyzed for different ratios of the operating and starting currents, input signal levels, and the inclination angle of the electron ...

The oscillation adjustment in clinotron

Journal of Communications Technology and Electronics, 2014
Linear and nonlinear stages of the oscillation adjustment in a model of a source of millimeter-wavelength radiation (clinotron) are analyzed using the nonstationary theory of interaction in a system consisting of a thick electron beam and a backward wave.

Spectral Characteristics of THz CW Clinotrons

IEEE Transactions on Electron Devices, 2020
The spectral properties of terahertz (THz) continuous-wave (CW) clinotrons have been studied both theoretically and experimentally. The resonant properties of clinotrons having strong influence on the spectral linewidth have been analyzed both for the frequencies below 150 GHz where resonances are determined by reflections of surface wave, and for THz ...

Experimental study on 0.1 THz Clinotron

IVEC 2012, 2012
A multimode theory of resonant backward wave oscillator with inclined electron beam — Clinotron is introduced. The mechanism of the efficiency enhancement due to mode interaction is unveiled through numerical simulation. The experimental setup for 0.1 THz Clinotron is being developed and the details of each part will be presented.

A nonstationary theory of the clinotron

Journal of Communications Technology and Electronics, 2011
Nonlinear equations for the analysis of the nonstationary operating mode of the clinotron are formulated. The linear stage of the transition to steady-state oscillations in the clinotron and the stability of the operating modes, which are found in the framework of the stationary single-mode theory, are considered.
