SLS – Swiss Light Source
The Swiss Light Source (SLS) is an X-ray synchrotron facility that has been operational since 2001. A comprehensive upgrade to a diffraction-limited ring was initiated in October 2023 and completed at the end of 2024. Currently new and upgraded beamlines are being commissioned in three phases. The upgrade ensures that research in photon science conducted at PSI remains at the forefront of rapid developments in medicine, bio- and pharmaceutical technologies, chemistry, physics, materials and advanced manufacturing.
Following the modernisation project, designated SLS 2.0, novel research and more precise investigations are now facilitated. With the implementation of this technical overhaul, SLS will continue to be positioned in the top tier of international synchrotron light sources.
