In the synchrotron X‐ray community, X‐ray absorption near‐edge spectroscopy (XANES) is a widely used technique to probe the local coordination environment and the oxidation states of specific elements within a sample. Although this technique is usually applied to bulk samples, the advent of new synchrotron sources has enabled spatially resolved versions of this technique (2D XANES). This development has been extremely powerful for the study of heterogeneous systems, which is the case for nearly all real applications. However, associated with the development of 2D XANES comes the challenge of analyzing very large volumes of data. As an example, a single 2D XANES measurement at a synchrotron can easily produce ∼10⁶ spatially resolved XANES spectra. Conventional manual analysis of an individual XANES spectrum is no longer feasible. Here, a software package is described that has been developed for high‐throughput 2D XANES analysis. A detailed description of the software as well as example applications are provided.

PyXAS –用于2D X射线近边缘光谱分析的开源软件包

在同步加速器X射线社区中，X射线吸收近边缘光谱（XANES）是一种广泛使用的技术，用于探测局部配位环境和样品中特定元素的氧化态。尽管此技术通常应用于大量样品，但新的同步加速器源的出现使该技术在空间上可以解析（2D XANES）。对于异构系统的研究，这种发展非常强大，几乎所有实际应用都是如此。但是，随着2D XANES的发展，分析大量数据面临着挑战。例如，在同步加速器上进行一次2D XANES测量可轻松产生约^{10 6}空间分辨XANES光谱。传统的手动分析单个XANES光谱不再可行。在此，将介绍为高通量2D XANES分析开发的软件包。提供了软件以及示例应用程序的详细说明。
