Advances in synchrotron imaging and computed tomography (CT) enable non-invasive, high-resolution 3D visualization of samples, including biological tissues, surpassing standard methods. This innovation generates massive data volumes, requiring tailored solutions for data capture, management, storage, and repositories for processed data and analysis code. These solutions enhance transparency...
The DAPHNE4NFDI initiative is transforming data management for photon and neutron science by implementing FAIR (Findable, Accessible, Interoperable, Reusable) principles across various experimental techniques. At the P10 beamline of DESY, we have deployed SciCat for SAXS/XPCS experiments, enhancing metadata ingestion and data accessibility. In parallel, the development of Xana 2.0 introduces...
In the frame of DAPHNE4NFDI, an X-ray absorption spectroscopy (XAS) reference database called RefXAS has been set-up where users are provided with well curated XAS reference spectra along with related metadata fields and online processing tools for visualizing the data. The developed online procedure enables users to submit a raw dataset along with its associated metadata via a dedicated...
Inelastic scattering is a fundamental technique for probing lattice dynamics and magnetic excitations, serving as a cornerstone in materials science and condensed matter research. While it has historically been linked to neutron scattering, recent innovations in modern synchrotron facilities have facilitated the acquisition of complementary x-ray scattering data, which are vital for...
Within the soft matter and liquid interfaces X-ray reflectivity Use Case 6, we develop a FAIR data pipeline for X-ray reflectivity at beamline P08, PETRA III. This includes automating electronic lab notebooks (ELNs) [1], metadata ingestion from the control system and IGSN creation for samples. Collaborating with DESY beamline scientists, experimental control group, and IT, we are implementing...
Understanding ultrafast structural and magnetic dynamics in materials is essential for advancing fields such as spintronics, quantum materials, and laser-driven phase transitions. Time-resolved X-ray scattering techniques at free-electron lasers (XFELs) provide a powerful tool to investigate femtosecond-scale structural and spin-related phenomena in thin films and nanostructures. In...
The university group at RWTH Aachen specializes in neutron TOF powder diffraction method development, primarily driven by the new concepts of the neutron time-of-flight diffractometer POWTEX, developed in collaboration with Forschungszentrum Jülich at FRM-II/MLZ in Garching. Unfortunately, no free neutrons were available in 2024. Within the DAPHNE project, we are therefore spreading our...
Tomography at neutron and photon sources is a ubiquitous tool with applications for a large variety of research domains. On the way to FAIR data, this use case is focusing on the metadata specification of tomography data from both photon and neutron sources, incl. the discussions for a common *nxs specification.
Within Use Case 10 the ICSP@FAU group works towards an automated, generic and FAIR data workflow for research institutes handling data from various sources. Key components of the workflow are a local NOMAD Oasis1, which is hosted by a local computer center and the utilization of the NeXus2 standard wherever possible. We present how we utilize and customize our NOMAD Oasis to fit the FAIR...
