PyXAS - an open-source package for 2D X-ray near-edge spectroscopy analysis

Area of Science:

• Materials Science
• Spectroscopy
• Synchrotron Radiation

Background:

• X-ray absorption near-edge spectroscopy (XANES) is crucial for analyzing material properties.
• Spatially resolved 2D XANES is powerful for heterogeneous systems but generates massive datasets.
• Manual analysis of 2D XANES data is becoming infeasible due to data volume.

Purpose of the Study:

• To introduce a novel software package for high-throughput 2D XANES data analysis.
• To provide a solution for managing and interpreting large-scale 2D XANES measurements.
• To demonstrate the utility of the software through example applications.

Main Methods:

• Development of a specialized software package for automated 2D XANES analysis.
• Implementation of algorithms designed for efficient processing of large spectral datasets.
• Validation of the software using real-world synchrotron XANES data.

Main Results:

• The developed software significantly accelerates the analysis of 2D XANES data.
• High-throughput analysis of complex heterogeneous samples is now feasible.
• The software effectively handles the ∼10^6 spectra typical of modern 2D XANES experiments.

Conclusions:

• The new software package overcomes the data analysis bottleneck in 2D XANES.
• This tool is essential for researchers studying heterogeneous materials with advanced synchrotron techniques.
• The software facilitates deeper insights into material structures and oxidation states.
