【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.更多还原

【Abstract】 The spectral resolution,spatial resolution of monochromatic X-ray images of a spectrograph based on convex crystal were discussed by ray tracing calculations taking into 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.更多还原
