Fe-Alloy X-Ray Diffraction Data from PETRA III Synchrotron, 2022

Raw X-ray diffraction (XRD) image data for iron-alloy samples collected at the P02.2 beamline of the PETRA III synchrotron at DESY in Hamburg, Germany, in 2022. The data was gathered by researchers from the University of Edinburgh to identify crystal structures and pressure-dependent unit-cell volume changes. These raw TIFF image files support the manuscript 'Sulfur-bearing hcp iron for Earth’s inner core'.

Use Cases

• Identify crystal structure of iron-alloy samples based on the XRD patterns mentioned in the description.
• Analyze pressure dependence of unit-cell volume based on the experimental data collection purpose.
• Validate or compare results from the associated manuscript 'Sulfur-bearing hcp iron for Earth’s inner core' using the supporting raw data.

Strengths

• Data originates from a high-brilliance third-generation synchrotron radiation source (PETRA III at DESY), suggesting high experimental quality.
• Data collection purpose is explicitly stated: to identify crystal structure and pressure-dependent unit-cell volume.
• Specific software for analysis is referenced (Dioptas, FIT2D), indicating established processing pathways.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
