MCP选通X射线皮秒分幅相机在ICF中的应用

摘要: 在上海“神光”装置上，首次将我国研制的首台MCP（微通道板）选通X射线皮秒分幅相机样机用于ICF（惯性约束聚变）激光等离子体物理诊断，在1.2ns内连续拍摄到激光注入孔等离子体辐射随时间变化的12幅二维空间分布图像，观测到等离子体喷射空间尺度随时间的变化过程。本文就该相机结构、测量原理和方法以及实验中获得的典型结果进行了分析讨论。

Abstract: The temporally and spatially resovled measurements of the laser produced plasma in ICF experiment were carried out at the Shenguang laser facility with a multiframe gated microchannel – plate (MCP) X – ray camera. During 1.2ns 12 frame images of the laser produced plasma source were obtained with the camera. The structure of the camera and measure pricinple were described.
