Measurement of a broadband high power gyro-TWA operating in W-band frequency

Research output: Chapter in Book/Report/Conference proceedingConference contribution book


In this paper experimental measurement of a W-band gyrotron travelling wave amplifier (gyro-TWA) which is upgraded to operate at a high output power and wide frequency band will be presented. The gyro-TWA based on 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 over 5 GHz. The design and upgraded results from the measurement of the amplifier and its components will be presented.
