高分辨球面弯晶单色成像系统研制与应用
Development and application of high resolution spherically bent crystal imaging system
摘要
利用石英(1010)球面弯晶作为X光成像元件,自主研制了应用于神光系列激光装置上的高分辨球面晶体X光成像系统。在实验中利用Mg作为背光材料,获得四周期网格子午方向放大倍数13.95倍、弧矢方向放大倍数11.61倍、中心能点1.472 keV、分辨率达到4 μm的X光图像,其谱分辨达到1.2×10-4。它为在激光惯性约束聚变内爆、流体不稳定性等物理实验中X光测量提供了重要诊断手段。
Abstract
High resolution spherically bent crystal imaging system has been development by using quartz 1010 crystal as X ray imaging component, and it has been applied in Shengguan laser facilties. By the imaging system, image of four cycle grid has been acquired by using Mg as backlight. The meridian magnification is 13.95 and the sagittal magnification is 11.61. The central energy is 1.472keV, and spectral resolution is 1.2×104. The resolution of the image is 4 micrometers. It is important diagnostics tool for monochromatic X ray image in implosion and fluid instability physical experiments.
