| 摘 要： | 为满足惯性约束聚变研究需要工作距离长、测谱范围宽的X射线诊断设备的独特要求，基于凸面反射几何原理研制了一台双通道弯晶谱仪。谱仪利用Si（111）及Qz（10－10）两种弯晶衍射X射线，并通过X射线CCD成功获得谱线图像，测谱范围从0.30 nm到0.65 nm。在激光装置原型诊断实验上得到应用。数据分析的结果证明实测谱线图像与理论模拟基本吻合。

| Abstract: | To satisfy the special requirement of the X-ray diagnosis instrument which needs long working distance and wide spectrum measurement in ICF, a new two-channel curved crystal spectrometer has been designed according to the reflecting geometry of convexity. The spectrometer diffracts X-ray by Si(111) and Qz(10—10) curved crystals with overlapping coverage of 0.30~0.65 nm, and the spectra are recorded by X-CCD detectors. The spectrometers has been applied to diagnostics with Shenguang-Ⅲ Prototype. Data analysis demonstrates that the spectra of experiment are accord with those of the theoretical simulation. |
