X-ray Photon Correlation Spectroscopy (XPCS) inverts the dynamic behavior of materials at the nanoscale by analyzing the "photon intensity fluctuations" in synchrotron X-ray scattering signals. The multitau algorithm (multi-tau algorithm) calculates lag times at different time levels through a "hierarchical grouping" strategy, which can cover a wide time range while controlling computational...

DREAM is one of the diffractometers in construction at the European Spallation Source (ESS), built by the consortium Forschungszentrum Jülich (Germany) and Laboratoire Léon Brillouin (France).
To ensure smooth operation even for the first-time users, the ESS Data Management and Scientific Computing centre is developing an integrated data pipeline linking all the steps of scientific data...

Neutron and x-ray scattering experiments traditionally rely upon
histogrammed data sets, which are analysed using least-squares curve
fitting of multiple probability distribution components to quantify
separately the various scientific contributions of interest. The main
advantage to this approach is the relative ease of deployment due to
its intuitive nature. Despite the great...

The High Energy Photon Source (HEPS) is a fourth-generation synchrotron radiation facility scheduled to enter formal operation in June 2026. Enabled by high brightness and advanced detector technologies, HEPS is expected to generate more than 200 PB of experimental data annually across 14 Phase-I beamlines. The wide range of experimental techniques, including imaging, diffraction, scattering,...

HoToPy is an open-source Python-based toolbox for X-ray holographic and tomographic data reconstruction. It features state-of-the-art phase retrieval algorithms for both the holographic and direct contrast imaging regimes, including nonlinear approaches and extended options for regularization and constraint sets. By combining automatic differentiation with provided fully differentiable forward...
