| 摘 要： | 利用新研制的紧凑型线性变压器驱动源（LTD）脉冲功率源二极管产生的电子束源，开展了S波段长脉冲相对论速调管放大器（RKA）的初步实验研究。采用无箔空心阴极和0.9 T恒流源引导磁场从LTD二极管引出了电压600 kV、束流6 kA、脉宽150 ns的环形电子束，该电子束经过1个同轴输入腔和2个同轴调制腔的调制后，产生了幅度5 kA、脉宽110 ns的基波调制束流，采用该调制束流驱动同轴微波提取腔，辐射输出了峰值功率820 MW/110 ns的辐射微波，效率28％，增益36 dB。同时，开展了重复脉冲RKA和相位特性的实验研究，重复频率10 Hz运行时，辐射微波达到800 MW/100 ns，相位抖动小于 20°。

| Abstract: | The initial experimental results of relativistic klystron amplifier (RKA) driven by linear transformer driver (LTD) pulse power supply are introduced. Hollow electron beam of 600 kV, 6 kA, and 150 ns is generated by foilless graphite cathode. Modulated current of 5 kA, 110 ns is obtained through an input cavity and two idler cavities. The modulated current generates peak microwave power of 820 MW, pulse width of 110 ns, and its efficiency is 28%, its gain is 36 dB. The phase and repetition operation characteristics of RKA are investigated in the experiments. The radiated microwave arrives 800 MW/100 ns, the phase shaking is less than ±20° at 10 Hz. |
