中文摘要：

为了诊断热核聚变等离子体状态，研制了用于热斑区等离子体诊断用的新型X射线谱仪，能够同时探测X射线光谱与聚爆靶图像信息。光谱检测功能由4块椭圆晶体分析器实现，分别覆盖2～20keV能带范围不同能带的X射；图像检测功能由分幅相机匹配小孔阵列成像完成，理想状态能够得到20幅不同时间的聚爆靶图像。在中物院“神光一Ⅱ”升级装置上进行了打靶实验，获取了X射线光谱与聚爆靶图像信号。分析了光谱及图像信息，并针对光谱仪漏光问题改进了谱仪结构。在神光一Ⅲ原型装置上进行了验证实验，获得比较理想的图像信号，信噪比（sNR）数据达到30．

英文摘要：

A novel X-ray spectrometer is designed to diagnose the plasma conditions. It can provide simul- taneously X-ray spectroscopy and plasma image information. Four eUiptically bent crystal analyzers are used to detect the X-ray spectroscopy in the range of 2-20 keV. The pinhole imaging systems coupled with gated micro-channel plate （MCP） detectors are developed to detect the image,and it allows 20 ima- ges to be collected in a single experiment. The experiments are conducted to demonstrate the utility of the spectrometer at ＂Shenguang-Ⅱ＂ upgrading laser facility in China Academy of Engineering Physics. The X-ray spectroscopy and hot sport image information are obtained by the spectrometer, and the pro- posed scheme can improve the capability of the spectrometer. Finally, experiments are done at ＂Shen- guang- Ⅲ＇laser facility,the ideal images are obtained,and the signal-to-noise ratio can raach 30.
