Abstract

Design and experimental results of a broadband, high power, millimetre-wave gyrotron traveling wave amplifier (gyro-TWA) operating in the 75-110 GHz frequency band and based on a helically corrugated interaction region (HCIR) and cusp electron beam source are presented. The second harmonic cyclotron mode of the electron beam was used to match the dispersion of an eigenwave in the HCIR, achieving energy transfer from the electrons to waves over a large frequency range. The gyro-TWA was measured to generate a maximum power of a few kWs with an unsaturated gain of 36-38 dB in the driving frequency band of 91-96.5 GHz.
