| 摘 要： | 介绍了一种采用三传输线型形成线压缩技术直接产生高功率亚纳秒脉冲的方法。给出了脉冲压缩的理论分析，设计了相应的脉冲压缩装置，并采用Pspice软件建立了电路模型，计算结果显示脉冲压缩装置的功率增益可达到2.25倍，验证了理论分析。基于现有的CKP1000超宽谱脉冲源，建立了完整的脉冲压缩实验系统并展开实验研究，结果表明:脉冲压缩装置在入射脉冲电压220 kV、脉宽5 ns的情况下，可产生峰值电压295 kV，半高宽约800 ps，前沿400 ps的亚纳秒脉冲，脉冲压缩装置的功率增益约为1.8倍，实验结果与理论值基本相符。

| Abstract: | A compact type high power subnanosecond pulse former which is based on triple transmission line type pulse compression is presented in this paper. The pulse former is designed and simulations are carried out through adopting Pspice software, the simulation has verified the analysis. An experiment based on the pulse power generator CKP1000 has been made to study the complete pulse-compression system. The results show that when the input pulse width is 5 ns, the output pulse can be compressed to be 800 ps in half-width and the front edge is only 400 ps. The power gain is up to 1.8. |
