摘　　要：大功率速调管中输出腔影响着整管的效率和峰值功率。为了提高效率和峰值功率,本文对工作在X波段的同轴多注速调管双间隙输出腔结构进行研究,通过理论结合仿真优化,得出合适的双间隙输出腔结构。最后与单间隙结构进行对比,证实双间隙输出腔可以提高输出腔的特性阻抗,降低间隙电场,展宽输出带宽。Output cavity has great impact on the efficiency and peak power of high-power klystron.To increase the peak power and improve efficiency,the double-gap coaxial output cavity in the X-band high-power multi-beam klystron is studied.An applicable structure can be achieved with parameter optimization,based on the theoretical calculation.With comparison of one-gap output cavity,it is confirmed that double-gap coaxial output cavity can increase the R/Q,decrease electric field of cavity gap,and extend bandwidth.
