High-performance compact X-ray absorption spectrometer

The invention provides a high-performance compact X-ray absorption spectrometer. The spectrometer is characterized by comprising an annular guide rail, three sliding modules are arranged on the annular guide rail, each sliding module is provided with an independent driving mechanism, and each driving mechanism drives the corresponding sliding module to slide in the circumferential direction alongthe annular guide rail; and the three sliding modules are respectively provided with a light source, a bent crystal analyzer and a detector. Compared with like spectrometers in the prior art, the spectrometer of the invention has high photon collection efficiency, high mechanical stability, compact motion scanning device and flexible acquisition mode. 本发明提供了一种高性能紧凑型X射线吸收光谱仪，其特征在于，包括环形导轨，环形导轨上设有三个滑动模块，三个滑动模块分别设有各自独立的驱动机构，由每个驱动机构驱动相应的滑动模块沿环形导轨在周向上滑动；三个滑动模块上分别设有光源、弯晶分析器、探测器。与现有技术相比，本发明具有高光子收集效率；高机械稳定性；紧凑的运动扫描装置；灵活的采集模式。
