The Swiss Light Source SLS has been in operation since 2001. This large research facility, which is unique in Switzerland, began a comprehensive upgrade to a diffraction-limited storage ring in October 2023. The machine upgrade was completed by the end of 2024, and the beamlines are now coming back online. With this upgrade, photon science at PSI will keep pace with the latest developments in science, technology, engineering and data processing.
Following the modernisation project, called SLS 2.0, novel research and more precise investigations are possible. With this technical overhaul, SLS will remain in the top tier of international synchrotron light sources. The project is being funded as part of the ERI Dispatch 2021-2024 programme.
