A highpower wideband gyroTWT amplifier

A tapered rectangular diskloaded gyroTWT amplifier with tapered guiding magnetic field and disk height, and partially decreasing period length is presented. The gain and the bandwidth are derived, the effect of the beam current, guide magnetic field, and input power on the output is numerically calculated. The output power is 88kW to 103kW with 16.63% to 24.11% relative bandwidth.
