Abstract

In this paper, the behavior of a gyro-traveling wave tube (gyro-TWT) amplifier, in which an axis-encircling electron beam synchronously interacts with the azimuthal modes of the vane-loaded cylindrical waveguide interaction structure, has been analyzed. The dispersion characteristics and gain-frequency response of the nearby waveguide modes (TE₀₁, TE₂₁, and TE₄₁) for the vane-loaded gyro-TWT amplifier have been presented. The gain-frequency response of the device has been studied for both the small-orbit and large-orbit configurations. It has been observed that the TE₄₁ mode of the device is well separated on the frequency scale for both these configurations. In addition, it has higher device gain in the large-orbit configuration when compared with the same obtained for the TE₀₁ and TE₂₁ modes.
