| 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. © 2006 IEEE. |
