A broadband, kW-level gyrotron traveling wave amplifier (gyro-TWA) in W-band was developed based on a helically corrugated interaction region and a cusp electron gun. Experiments were carried out to demonstrate the versatility of the gyro-TWA and to investigate its broad instantaneous amplification bandwidth. Following the successful prototyping, research is being carried out to improve the stability of the amplifier and widen its capability for continuous wave operation for long-range high-data-rate communication applications.
