    Abstract

    In this paper initial experimental results of a W-band gyrotron travelling wave amplifier (gyro-TWA) which is upgraded to operate at a high pulse repetitive frequency of 2 kHz will be presented. The gyro-TWA based on a helically corrugated interaction region and cusp electron beam source can output a maximum power of 5 kW at its centre frequency of ∼94 GHz with an instantaneous frequency bandwidth of 10 GHz. The design, upgrade and performance of the amplifier and its components will be presented.
