最近在国家同步加速器光源的弯曲磁体光束线 X27A 上安装了一条新的硬 X 射线显微光谱光束线，该光束线的研究重点主要针对环境、地质和材料科学界。该仪器除了提供高 X 射线通量吞吐量和可选择的能量分辨率外，还使用消色差动态弯曲柯克帕特里克-贝兹镜提供适中的约 10μm 空间分辨率。中等空间分辨率和高通量通量之间的平衡，与液氮冷却的 13 元件能量色散高纯锗探测器相结合，特别适合使用荧光 X 射线吸收精细结构检测模式研究稀释和薄膜系统。在本文中，我们报告了该仪器的设计和性能，并重点介绍了该设施最近进行的一项实验研究。
A new hard X-ray micro-spectroscopy beamline has recently been installed at bending-magnet beamline X27A at the National Synchrotron Light Source, where the focus of research is primarily directed towards the environmental, geological and materials science communities. This instrument delivers moderate, ∼10μm spatial resolution using achromatic dynamically bent Kirkpatrick–Baez mirrors, in addition to providing high X-ray flux throughput and selectable energy resolution. The balance between moderate spatial resolution and high flux throughput, in combination with a liquid nitrogen-cooled 13-element energy-dispersive high-purity germanium detector, is particularly well suited to the investigation of dilute and thin-film systems using the fluorescence X-ray absorption fine-structure mode of detection. In this paper, we report on the design and performance of this instrument and highlight a recent experimental study undertaken at this facility.
