Ultrafast Pulsed Laser Annealing of Pd100-xSix Thin Films: raw and processed XRD data from PETRA III P07 experiment

This repository contains the underlying research dataset for the publication "Ultrafast Pulsed Laser Annealing of Pd100-xSix Thin Films" (Acta Physica Polonica A, Vol. 148, No. 3, 2025). 

The data comprises raw and processed high-energy synchrotron X-ray diffraction (XRD) measurements collected at beamline P07 (High-Energy Material Science, Experimental Hutch 2) of the PETRA III storage ring at DESY (Hamburg, Germany) under Proposal ID 20230294 (Beamtime ID 11017285). The experiment utilized a Dectris Pilatus CdTe 2M 2D detector to record spatial area mapping profiles crossing directly through laser-irradiated spots on Pd100-xSix thin films of various chemical compositions (pure Pd reference, Pd97Si03, Pd95Si05, and Pd90Si10). 

The dataset is systematically organized into four separate components:
1. Calibration data: PyFAI .poni geometry files, master mask arrays, and CeO2 standard reference states.
2. Raw data: Unprocessed 2D Pilatus detector image sequences and experimental runtime logs mapping the full spatial profiles.
3. Integrated 1D patterns: Azimuthally integrated Intensity vs. 2-Theta, including raw integration matrices, global integration parameters (JSON format), and files where the substrate background was subtracted.
4. Data analysis workflows: Working directories for Profex/BGMN Rietveld phase refinement files, structure definitions, and the specific amorphous background pattern (bkg.xy, corresponding to an unannealed Pd83Si17 sample) used to isolate thin-film metallic glass fractions.

While the raw sequences and integrated patterns contain the complete sequence of spatial steps recorded across the sample area (covering the area far from the laser center, passing through the boundary, and moving completely through the irradiated spot zone), only a selected subset of scan coordinates was utilized for the final figures in the journal publication. All files are provided in their entirety to ensure complete open-science transparency.

Full details regarding structural tracking parameters, coordinate file tracking nomenclature, and technical hardware setups are outlined in the accompanying plain-text README.txt file.
