The Advanced Photon Source (APS) at Argonne National Laboratory (ANL) has completed a major upgrade that included replacement of the storage ring delivering greatly increased brightness, coherence, and high-energy x-ray capabilities, enabling transformative new scientific opportunities across the APS experimental program. These advances, together with new state-of-the-art high-bandwidth...

The European XFEL, a world-leading X-ray Free Electron Laser situated in the Hamburg-area, Germany, offers a unique 4.5 MHz burst pulse structure that enables users from across the globe to conduct scientific measurements during typically one-week-long beam times. These measurements are supported by facility staff throughout, and each of the 7 instruments can be reconfigured significantly for...

Modern detectors typically consist of multiple modules to achieve large areas and generate increasingly high data rates. Synchronization across these modules, together with efficient real-time data handling, is therefore essential for enabling responsive and data-driven experiments.

ASAP::O, a high-performance streaming framework designed for low-latency data transport and scalable...

Abstract

Ultra-fast time-resolved synchrotron computed tomography (CT) can acquire up to 1000 tomographs per second, enabling the study of highly dynamic processes but producing data streams that challenge transmission, reconstruction, analysis, and storage. To support smart experiments and rapid feedback at the TOMCAT beamlines of the Swiss Light Source, we developed a live...

The European Spallation Source (ESS) will initially consist of 15 scientific
instruments. These cover diverse scientific scopes—such as neutron spectroscopy,
imaging, diffraction, and reflectometry—each requiring completely different
instrument designs and...

The Karabo data acquisition (DAQ) at the European XFEL is capable of data reduction based on external information like beam conditions and shutter positions. To cope with the storage challenges imposed by the next generation of the AGIPD detector, i.e. almost 1 GB/s for each of its 56 modules, it will be necessary to base the decision to store or reject data frames on near-realtime data...
