【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-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-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。

The spectrum detection function is realized by four elliptical crystal analyzers, which cover the X-ray emission of different energy bands in the 2~20keV band range respectively. The function of image detection is accomplished by the matching aperture array of the splitter camera, and 20 target images with different time can be obtained in ideal state. The shooting experiment was carried out on the "Shenguang 鈪，
