摘要
为实现惯性约束聚变(ICF)实验中同时获取靶点的X射线1维动态和2维静态积分图像, 提出了一种全新的X射线图像采集方法。结合成像板与X射线条纹相机的工作特性, 通过在阴极狭缝前精密耦合成像板, 实现X射线图像到达狭缝的同时采集其外围区域的静态积分图像。该方法具有对靶点X射线图像的1维动态与2维静态图像对比分析、成像系统像面位置精密空间定位的功能。利用该方法在神光Ⅱ装置上实现搭载Kirkpatrick-Baez(KB)显微镜获得内爆靶球压缩流线图, 并应用于流体不稳定性实验中。
Abstract
A new precision coupling technology of image plate and X-ray streak camera is developed to obtain the images of target in inertial confinement fusion experiments. Combining the characteristics of image plate and X-ray streak camera, one-dimensional dynamic image and two-dimensional static integral image of peripheral area of the cathode slit can be obtained at the same time, with precision coupling of an image plate in front of the slit. The technology can be used in the comparison of two-dimensional static and one-dimensional dynamic images. It can also be used in the precision positioning of image system. With this technology and Kirkpatrick-Baez microscope, implosion streamlines and Rayleigh-Taylor instability images have been acquired on Shenguang-Ⅱ laser facility.
