A bent-crystal spectrometer based on the Rowland circle geometry has been installed and tested on the BM30b/FAME beamline at the European Synchrotron Radiation Facility to improve its performances. The energy resolution of the spectrometer allows different kinds of measurements to be performed, including X-ray absorption spectroscopy, resonant inelastic X-ray scattering and X-ray Raman scattering experiments. The simplicity of the experimental device makes it easily implemented on a classical X-ray absorption beamline. This improvement in the fluorescence detection is of particular importance when the probed element is embedded in a complex and/or heavy matrix, for example in environmental sciences.
一种基于罗兰圆几何结构的弯晶光谱仪已在欧洲同步辐射装置的BM30b/FAME光束线上安装并测试，以提高其性能。该光谱仪的能量分辨率允许进行不同类型的测量，包括X射线吸收光谱、共振非弹性X射线散射和X射线拉曼散射实验。实验装置的简单性使其易于在传统的X射线吸收光束线上实现。当被探测元素嵌入复杂和/或重基质中时，例如在环境科学中，这种荧光检测的改进尤为重要。
