摘　　要：介绍Ｌ波段强流相对论速调管放大器输入腔的数值分析、新型的结构设计和实验调试及其应用等方面的情况，对输入腔进行了特别的结构设计，解决了大耦合孔对谐振腔参数的不良影响，设计符合ＲＫＡ应用的要求。均匀电子束经过输入腔后，得到了约６％的最大基波调制电流深度。Simulations, designs and experiments of the input cavity of an L-band intense relativistic klystron amplifier are described in this paper. Influences of large coupling holes on the microwave input cavity parameters which include resonant frequency, symmetry and uniformity of the electric field in the gap region were overcomed with axial symmetric slots as fig.1. They have gotten a 6% fundamental harmonic modulated current after the electron beams got through the input cavity gap.
