Control of sub-terahertz gyrotron frequency by modulation-anode voltage: Comparison of theoretical and experimental results

Abstract

This paper presents a comparison of simple self-consistent theory data and experimental results aimed to study the influence of the anode voltage on the frequency of the subterahertz gyrotron with the goal of frequency stabilization. Numerical simulations of the electron beam formation and beam-wave interaction in a 0.26 THz gyrotron are performed. The experimental dependence of the gyrotron frequency tuning on mod-anode voltage is in agreement with theoretical predictions.
