摘要

基于X射线布喇格衍射理论

研制了球面弯曲晶体分析器

用于研究和诊断惯性约束聚变的聚爆靶等离子体的形状、分布及稳定性。分析器的核心器件是石英球面弯晶

弯曲晶体半径为143.3 mm。首次利用石英球面弯曲晶体进行了单色X射线背光成像实验。采用接收面积为40 mm30 mm的磷屏成像板作为接收装置

得到了清晰的铬靶单色X射线二维背光聚焦成像。对所得实验弧矢方向区域谱线的分析显示

石英球面弯曲晶体得到的X射线背光成像的空间分辨率约为83.3 m。实验结果表明该球面弯曲晶体适合于X射线的背光诊断研究。

Abstract

A novel spherically bent crystal analyzer was developed based on the X-ray Bragg diffraction theory to study and diagnose the distribution

stability and the shape of a plasma of pellet implosion in the Inertial Confinement Fusion (ICF). The key component of the crystal analyzer is a spherically bent -quartz crystal with a radius of 143.3 mm. The spherically bent -quartz crystal was used to carried out a monochromatic X-ray backlighting imaging experiment in the Research Center of Laser Fusion

China Academy of Engineering Physics(CAEP). The clear two-dimensional monochrome X-ray backlighting image of a chrome target was obtained on an imaging plane of 40 mm30 mm. By analyzing the spectral information of a sagittal direction in the experiment

it is demonstrated that the spherically bent -quartz crystal shows his spatial resolution to be 83.3 m and it could be used for research of the monochromatic X-ray backlighting imaging.
