摘要
介绍了所设计自己编程的示波器照片图像处理系统 ,分析在闪光 - 1加速器上所做的工作腔体内内电磁脉冲 (IEMP)环境参数的实验研究中获得的实测波形的频率谱特性 ,比较了不同状态下IEMP对应的时域、频域特性变化 ,初步总结了 IEMP频谱特性的一般规律。最后 ,以理论分析为基础 ,从频率域研究的角度揭示 IEMP的本征属性及锁膜调相机制。并以分析结果为依据 ,评估业已采用的加固措施。
The characteristic of frequency spectrum of the inner electro magnetic pulses from the working chamber of our accelerator Flash I are analysed by use of an image processing system developed by ourselves, and their general laws are summed up through comparing both temporal and frequency spectrum under different conditions. Then, based on theoretical analysis, the intrinsic attributes and the mechanism of mode locking and phase modulating are revealed in terms of frequency spectrum, the consolidating measures which have gone into applications are accessed, and a frequency spectrum criteria of consolidation against nuclear is suggested.
