High power microwave pulse compression of energy doublers

为了开展S波段能量倍增器脉冲压缩实验,对能量倍增器进行了冷测和热测工作,主要包括对能量倍增器的指标、参数的测量以及在高功率下对能量倍增器的输出功率、功率增益等参数的测量。实验中,完成了微波固态源系统的改造,研制了同步信号控制器,研究了输入输出脉冲宽度对输出峰值功率的影响,并对实验中可能的射频击穿问题进行了研究。在输入功率5 MW时,得到了功率增益7.122,输出脉宽260 ns,输出峰值功率35.35 MW。

In the S-band Stanford linear accelerator center energy doublers（SLED） compression experiment,the SLED was measured in low power and high power,including its parameters,output power and power amplification.In the experiment,the microwave source system was modified and a synchronizing signal generator was developed.The influence of the input power width upon the output power and the RF breakdown in the experiment were also studied.When the input power was 5 MW,a power amplification of 7.122 at 260 ns and a peak power of 35.35 MW were acquired.
