主要介绍了为“强光一号”加速器丝阵负载Z箍缩实验设计的可见光图像诊断系统,系统时间分辨约为5 ns,空间分辨约为6.5 lp/mm,光谱响应范围365~750 nm。系统能够满足从早期单丝电离到等离子体柱飞散整个Z箍缩过程的诊断要求,给出了系统在Z箍缩实验中获得的丝阵负载内爆图像序列,并对其反映的内爆现象进行了初步的唯象分析。
This paper introduces a visible light image diagnosis system designed for Z - pinch experiment of “HG - 1” accelerator wire array. The time resolution is about 5 ns, the spatial resolution is about 6.5 lp / mm and the spectral response range is from 365 to 750 nm. The system can meet the diagnostic requirements of the whole Z-pinch process from the early monofilament ionization to the plasma column scattering. The image sequence of the array loading obtained by the system in Z-pinch experiment is given and the implosion phenomenon A preliminary phenomenal analysis was carried out.
