摘要：

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 angstrom and has a resolving capability of delta lambda/lambda on the order of 3%. Initial results from space resolved impurity measurements from NSTX are described in this paper. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3474661]
