  • Abstract
    Wideband operation of a gyro-TWT (traveling wave tube) with a dielectric loaded waveguide is demonstrated. Fast wave interaction allows the beam quality requirements to be reduced. Self-consistent nonlinear simulation has been performed and shows that an instantaneous bandwidth of 20% with a moderate efficiency of 13% can be achieved by using a low alpha beam with a 2% axial velocity spread. Parameters for a proposed Ka-band amplifier are given.<>
