High-Pressure Cerium Hydride X-ray Diffraction Maps for Phase Identification

A dataset of spatially resolved X-ray diffraction patterns from a high-pressure cerium hydride sample, produced using 4th generation synchrotron facilities. The data, uploaded by Lucas H. Francisco in March 2026, is 99.2 MB in size and is intended to challenge traditional analysis methods for identifying elusive crystal phases in colossal datasets.

Use Cases

• Developing physics-informed similarity measures for X-ray diffraction curves.
• Applying unsupervised clustering algorithms to identify independent structural phases within spatial maps.
• Investigating synthesis inhomogeneities in superhydride superconductors.
• Extending analysis frameworks to any correlated set of curves tied to specific entities.

Strengths

• Data originates from high-resolution X-ray mapping enhanced by 4th generation synchrotron facilities.
• The analysis approach described is physics-informed, designed for identifying elusive phases.
• Dataset size is 99.2 MB, indicating a substantial collection of diffraction patterns.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the specific high-pressure cerium hydride sample studied.
