Swiss Light Source - SLS
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
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.
Kurzfilm eines magnetischen Nanowirbels
Mit einer neu entwickelten Untersuchungsmethode konnten Forschende die magnetische Struktur im Inneren eines Materials mit Nanometer-Auflösung abbilden. Ihnen gelang ein kurzer «Film» aus sieben Bildern, der erstmalig in 3-D zeigt, wie sich winzige Wirbel der Magnetisierung tief im Inneren eines Materials verändern.
Soft X-ray Laminography: 3D imaging with powerful contrast mechanisms
3D imaging using synchrotron radiation is a widely used tool that allows access to the inner structure of complex objects. An international and interdisciplinary consortium of scientists from the Swiss Light Source (PolLux and cSAXs), the Friedrich-Alexander-Universität Erlangen-Nürnberg, and the University of Cambridge developed the new 3D imaging technique of Soft X-ray Laminography (SoXL). SoXL allows for the investigation of thin and extended samples while taking advantage of the characteristic absorption contrast mechanisms in the soft X-ray range, providing 3D information with nm spatial resolution.
