A fourth issue of the Solaris News has been published . This time, we focus on the X-ray multimodal imaging technique, and the update from the project team on the pilot experiment with the cosmetics industry completed within the framework of the Sylinda project. We also report on our participation in the Life Science Open Space and break the news about prof. Jakub Szlachetko, the Director of SOLARIS, being chosen to lead League of Accelerator – Based Photon Sources (LEAPS) in 2025.
