摘要
在回旋速调放大器自洽非线性大信号理论分析和数值计算的基础上,给出了一支Kα波段TE01模4腔基波回旋速调放大器的设计方案,并完成了样管的研制.同时对样管进行了热测实验,得到了如下实验结果:注电压为70kV,电流为10A,输入功率为60W,磁场强度1.31T,中心频率34GHz,峰值功率245kW,平均功率大于3kW,增益36.1dB,效率35%,3dB带宽大于280MHz.
Based on the analyses and the calculations of the gyroklystron amplifier＇s self-consistent nonlinear theory,a scheme of Kα-band,TE01 mode,four-cavity fundmetal wave gyroklystron is designed.At the same time,a gyroklystron amplifier is made and tested.The hot test experiment shows that the gyroklystron amplifier can produce 245 kW peak output power,and 3 kW average power at a 35% efficiency and saturated gain of 36.1 dB at central frequency 34 GHz,when using 60 W driving power,and a 70 kV,10 A annular electron beam in a magnetic field of 1.31 T.The full width half maximum（FWHM） bandwidth is higher than 280 MHz.The amplifier is zero-drive stable.Experimental results are found to be in excellent agreement with theoretical predictions.
