| 摘 要： | 利用场匹配理论，建立了具有突变结构谐振腔的级联散射矩阵。通过数值计算，研究了具有突变结构谐振腔中各模式的反射相移随漂移段半径变化、工作模式的反射相移随腔体半径的变化、腔体中各模式的传播常数随腔体半径的变化、谐振腔的腔体长度和半径的关系，并完成了Ka波段TE01模回旋速调管的输入腔、群聚腔、输出腔的设计。同时给出了一支Ka波段TE01模四腔基波回旋速调管高频系统和整管的优化设计方案。PIC模拟表明：在中心频率34GHz，注电压70kV，注电流11A的情况下，获得了输出功率390kW，饱和增益42.9dB，电子效率50.6%，3dB输出带宽360MHz的结果。 通过样管的热测实验显示在34GHz，注电压70kV，注电流11A，获得了301kW的稳定输出脉冲峰值功率，41.8dB的增益，39.1%的效率，285MHz的3dB输出带宽。

| Abstract: | he scattering matrix for the cavity with abrupt changes in radius in the gyroklystron was built with the mode-matching technique. The variations of the resonance characteristic of the cavity modes with the length and radius of the cavity have been studied. The cavities for input, bunching and output of the Ka-band TE01 mode in the gyroklystron have been designed and fabricated.The designed amplifier, as indicated by the PIC simulation, was expected to produce 390 kW peak output power, saturated gains of 42.9 dB and 50.6% efficiency at center frequency 34 GHz and 70kV, 11A annular electron beam. The full width half maximum (FWHM) bandwidth is greater than 360 MHz. The hot test shows that the fabricated gyroklystron amplifier has actually produced 301 kW peak output power, 39.1% efficiency and saturated gains of 41.8 dB at center frequency 34 GHz and 70 kV ,11 A annular electron beam . The full width half maximum (FWHM) bandwidth is greater than 285 MHz. |
