Swiss Light Source - SLS
COVID-19: SLS is in full 24/7 user operation
The SLS is in full 24/7 user operation with safety measures against COVID-19 infections in place. Currently international business travel is still restricted and thus not all users can reach Switzerland. Please see below or on the user office pages further information entitled 'Important information for SLS and SwissFEL users'.
The Swiss Light Source (SLS) at the Paul Scherrer Institut is a third-generation synchrotron light source. With an energy of 2.4 GeV, it provides photon beams of high brightness for research in materials science, biology and chemistry.
SLS is part of the Photon Science Division. The facility has world-leading instruments at its beamlines for unraveling the structure of proteins, for in-depth 3D imaging of matter, and for investigating how the electrons of atoms and molecules keep matter together and render it properties such as magnetism and electron conduction at zero resistance (‘superconductivity’).
- The beamlines for protein structure determination are intensively used by pharmaceutical companies in Switzerland and abroad. SLS is also leading in the development of pixelated X-ray detectors. The company DECTRIS has been spun off from these activities.
- In something as complex as a human being structures and processes occur on all length scales from macroscopic down to atomic dimensions. The SLS host a variety of techniques to address problems on different length scales.
- Materials with new, functional properties are the scope of intense research, since they offer fascinating insights into fundamental interactions and hold promise for advanced technologies which is highly needed. The SLS host world-leading capability in advanced materials spectroscopy ranging from photoemission spectroscopy, over spectromicroscopy to different X-ray absorption, scattering and diffraction techniques.
- A further focus is to provide advanced micro- and nanofabrication technologies to academic and industrial users, in particular in the area of polymer nanotechnology.

Priority access call for work on combating COVID-19 continues
On January 30th, 2020, the WHO declared the recent outbreak of coronavirus disease 2019 (COVID-19), a public health emergency of international concern. It declared that there is an urgent need to improve our understanding of the newly identified virus and its possible future evolution as well as to contain the spread; to develop precise diagnostics and treatment, and to improve the public health response and patient care.
The COVID priority access call continues and is still open in 2021.
PSI equips the Swiss Light Source SLS for the future
Green light for SLS 2.0: The planned upgrade of the Swiss Light Source SLS can proceed; the funding is provided for within the framework of the ERI Dispatch for 2021-2024, which has been approved.
Look Inside a Chemical Reactor
Operando X-ray spectrotomography allows scientists to look inside of functioning chemical reactors. A research team at Karlsruhe Institute of Technology (KIT), at Paul Scherrer Institute PSI and at the European Synchrotron Radiation Facility (ESRF) in France have employed this method successfully.
