丝阵负载Z箍缩可见光图像诊断系统
Optical image diagnostic system for wire array Z-pinch
-
摘要: 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。Abstract: An optical imaging diagnostic system was developed for “QiangGuang-I” wire array Z-pinch experiments. The system, with a gate of 5 ns and spatial resolution of 6.5 lp/mm, is sensitive to the wavelength of 365~750 nm. The system can be used to study the whole process of wire array Z-pinch, from the discharge of single wire to the breakdown of plasma column. The last image series of wire array Z-pinch plasma measured by this system are shown and phenomenally discussed.
