摘要

介绍了一种工作在75 ~ 110 GHz频段、基于螺旋波纹相互作用区(HCIR)和尖端电子束源的宽带、高功率毫米波回旋管行波放大器的设计和实验结果。电子束的二次谐波回旋模式用于匹配HCIR中本征波的色散，实现了在大频率范围内从电子到波的能量转移。经测量，陀螺- twa在91-96.5 GHz的驱动频段产生的最大功率为几kw，不饱和增益为36-38 dB。

Demonstration of a high power broadband mm-wave gyro-TWA

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.
