中文摘要：

考虑晶体摇摆曲线的影响,用光线追迹方法讨论了凸晶摄谱仪的能谱分辨率、单色图像径向空间分辨本领以及晶体与X射线源之间的距离对它们的影响.根据讨论建立了云母凸晶摄谱仪,在“强光一号”装置上对系统进行了成功地测试,获得铝丝阵负载Z箍缩等离子体X辐射单色图像.时间积分图像表明,Z箍缩Al等离子体K壳层Lyα和Heβ线辐射来自等离子体核心直径约2.3mm的区域.

英文摘要：

The spectral resolution, spatial resolution of monochromatic X-ray images of a spectrograph based on convex crystal were discussed by ray tracing calculations taking inlo consideration the effect of rocking curve of the crystal. A mica convex crystal spectrograph was designed and then tested successfully on ＂QiangGuang-1＂ pulsed power facility. Time integrated monochromatic X-ray images of Al Z-pinch plasmas showed the X-ray line emissions of K-shell came from the core region of a diameter of about 2.3 mm.
