摘 要:叙述了双通道椭圆弯晶谱仪的结构原理,详细阐述了天然云母弯晶分析器作为色散元件的制作过程.并在星光Ⅱ激光装置上对金平面靶进行了打靶实验,得到金平面靶的谱线图像数据.为了分析谱线图像数据相互混叠、相互交错的原因,对丹巴天然云母还进行了X射线单晶衍射实验与表面观察实验.实验结果表明,选择丹巴天然云母作为色散元件是造成谱线图像相互混叠、相互交错的根本原因.The structure and principle of double-channel elliptical crystal spectrometer are presented. The whole process of manufacturing dispersive element with natural muscovite is specified. The instrument was applied to diagnose plasma produced by laser on "XG-Ⅱ" facility and the spectrum of fiat Au was obtained. In order to analyze the reason of unsatisfactory pattern in which spectral lines interveined each other, X-ray diffraction experiment and observating surface of muscovite were conducted. The experimental results show that using such natural muscovite as dispersive element is the real reason for interlaced spectrum.
