SOLEIL II: enhancing data management and computing for tomorrow’s science

Operational since 2008, SOLEIL [1] offers users access to a wide array of experimental techniques through its 29 beamlines, covering a broad energy spectrum from THz to hard X-rays. In response to evolving scientific and societal needs, SOLEIL is undergoing a major upgrade through the SOLEIL II project. This transformative initiative includes the development of a new Diffraction Limited Storage Ring (DLSR) [2], designed to dramatically increase brilliance, coherence, and flux. The upgrade also encompasses the modernization of beamlines to support state-of-the-art experimental techniques, along with a comprehensive digital transformation centered on data and user-oriented workflows. This poster presents the current status of the digital transformation efforts within the SOLEIL II framework. It outlines the project's overall progress, with a particular focus on advancements in computing and data management. A central element of this transformation is the implementation of a unified Data Platform. Key developments include the deployment of a data catalog, upgrades to the IT infrastructure, user interface (UI) research, and the integration of robotics. The platform leverages shared infrastructure and software patterns to support both beamline and accelerator teams. Additionally, ongoing evaluations of data streaming technologies—such as ASAPO, LIMA2, and Dranspose—aim to enhance real-time data acquisition and processing capabilities.
