The present work focuses on the microstructure evolution of an aluminium 6082 alloy during the homogenization treatment. In-situ high-energy X-ray diffraction (HEXRD) measurements enable the time-resolved study of the evolution of primary phases like β-Mg2Si and silicon and the nucleation of new precipitates, such as α-Al15(Fe,Mn)3Si2 dispersoids and metastable B′-Al4Mg8Si7.

Advancements in synchrotron and X-ray free-electron sources and associated developments in instrumentation and techniques offer many new possibilities for researchers. At the same time there is increasing demand and pressure to implement the FAIR data principles by which data should be made Findable, Accessible, Interoperable and Reusable. [...]

Under the DAPHNE4NFDI consortium, RefXAS has evolved as a comprehensive open-access database for X-ray absorption spectroscopy (XAS). We have implemented a platform that allows users to submit raw datasets and associated metadata via a web interface. [...]

The Turkish Soft X-ray Photoelectron Spectroscopy (TXPES) beamline project at the Synchrotron-light for Experimental Science and Applications in the Middle East (SESAME) synchrotron, led by Turkish Energy Nuclear and Mineral Research Agency (TENMAK) is an important development as it marks SESAME’s first beamline fully designed, manufactured, and installed by a member country, Turkiye in 2025. TXPES will be installed on the free branch of the Helmholtz-SESAME Soft X-Ray Beamline (HESEB) and will share the same photon source and monochromator. [...]

The CODEX-β apparatus is a demonstrator for the proposed future CODEX-b experiment, a long-lived-particle detector foreseen for operation at IP8 during HL-LHC data-taking. The demonstrator project, intended to collect data in 2025, is described, with a particular focus on the design, construction, and installation of the new apparatus..

The x-ray spectra recorded with high-resolution spectrometers onboard satellite observatories contain valuable information about a wide range of different hot astrophysical environments. However, our ability to extract this information is currently often limited by the availability and accuracy of atomic data, as they are the foundation of plasma models. [...]

As a generalization of graphs, hypergraphs are widely used to model higher-order relationsin data. This paper explores the benefit of the hypergraph structure for the interpolationof point cloud data that contain no explicit structural information. [...]

The availability of intense X-ray beams at megahertz repetition rate allows for new scattering and imaging experiments using the unique pulse train structure of the European X-ray Free-Electron Laser (EuXFEL). However, the resulting heat load can pose challenges for X-ray optics and potentially limit the efficiency. [...]

Percival is a CMOS-based imager with 2 megapixels, also called P2M, designed for photon science experiments. The first generation of the P2M sensor showed some performance issues. [...]

Recent upgrades in synchrotron radiation facilities, which now produce highly brilliant and coherent beams, result in a broader array of experiments challenging the available detectors. In X-ray Absorption Fine Structure (XAFS) experiments, detector performance is often a limiting factor, especially with the high photon fluxes from upgraded facilities. [...]
