We consider the possibility to create a gyrotron with smooth mechanical frequency tuning on the basis of multimirror quasi-optical resonators. The two-dimensional problem of finding igenmodes at the open quasi-cylindrical resonator of such a type is

A design of a new powerful high-frequency short-pulse coaxial-cavity harmonic gyrotron operating at first, second, and third harmonic is presented. The design includes the analysis of mode competition between the fundamental and higher harmonic modes

It is shown that the efficiency of a coaxial gyrotron can be increased considerably by applying only independently appropriate voltages to its electrodes (without modifying design). The proposed scheme is also suitable for stepwise frequency tuning a

A 140-GHz, 1.5-MW, TE/sub 28,16/-coaxial cavity gyrotron with a dual RF beam output has been designed, built, and tested. For the first time, the generated RF power has been split into two parts and coupled out through two RF output windows in order

This paper investigates coaxial gyrotron cavities with longitudinal slots on the inner conductor as a means to reduce the number of possible competing modes. In the analytic theory the corrugated surface is treated as a homogeneous impedance surface

A general theory is developed for self-consistent calculations of mode competition in a gyrotron with nonfixed axial structure of the RF field for arbitrary cyclotron harmonics. The theory is applied to the gyrotron operating at the Kernforschungszen

In this paper , the feasibility of a super power coaxial gyrotron at 5 MW, 170 GHz, operating in the TE/sub 44,44/ mode is presented as a small step towards a big leap from 2MW to 5 MW power levels. Gyrotrons are high power microwave sources widely e
