摘要

一种基于螺旋波纹相互作用区的w波段回旋管行波放大器(gyrotron行波放大器，陀螺- twa)实现了3.4 kW的不饱和输出功率，增益高达37 dB, 3db频率带宽至少为5.5 GHz。在实验中发现，陀螺- TWA可以在一系列不同的电子束下工作。通过对多频信号的放大，验证了陀螺- TWA的频率敏捷性。

Amplification of W-band multi-frequency signals using a gyro-TWA

A W-band gyrotron traveling wave amplifier (gyro-TWA) based on a helically corrugated interaction region achieved an unsaturated output power of 3.4 kW with a gain of up to 37 dB and a 3 dB frequency bandwidth of at least 5.5 GHz. In the experiments it was found that the gyro- TWA can be operated with a range of different electron beams. Also the frequency agility of the gyro- TWA was demonstrated by the amplification of multi-frequency signals.
