A free standing transmission grating based imaging spectrometer in the extreme ultraviolet range has been developed for the National Spherical Torus Experiment (NSTX). The spectrometer operates in a survey mode covering the approximate spectral range from 30 to 700 Å and has a resolving capability of δλ/λ on the order of 3%. Initial results from space resolved impurity measurements from NSTX are described in this paper.
为美国国家球形环面实验（NSTX）研制了一种基于透射光栅的独立式极紫外成像光谱仪。该光谱仪以普查模式运行，覆盖约30至700埃的光谱范围，分辨能力δλ/λ约为3%。本文介绍了NSTX空间分辨杂质测量的初步结果。
