Swiss Light Source - SLS

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.
The SYN-department comprises four laboratories. Three laboratories (LSB, LSC, LSK) are centered around the Swiss Light Source (SLS). The fourth is the Laboratory for Micro- und Nanotechnology (LMN).

The operation of the beamlines at the SLS is split into three thematic areas:

Jurassic Welsh mammals were picky eaters, study finds

Media Releases Research Using Synchrotron Light

New analyses of tiny fossil mammals from South Wales are shedding light on the function and diets of our earliest ancestors, a team led by researchers from the Universities of Bristol and Leicester report in the journal Nature. The team used CT scanning with synchrotron X-rays at PSI’s Swiss Light Source to reveal in unprecedented detail the internal anatomy of the mammals’ tiny jaws.

Insulator makes electrons move in an ordered way

Media Releases Research Using Synchrotron Light Materials Research Matter and Material

Researchers at the PSI, the EPFL and the Chinese Academy of Science, have proven that the material SmB6 shows all the properties of a so called topological insulator – a material with electric currents flowing along its surface with all of them being polarized. Here, the property is very robust, i.e. the only current that can flow is spin polarized and is not easily destroyed by small irregularities in the structure or composition of the material. Spin polarized currents are necessary for spintronics, electronics using the electrons’ spin.

Fast scanning coherent X-ray imaging using Eiger

The smaller pixel size, high frame rate, and high dynamic range of next-generation photon counting pixel detectors expedites measurements based on coherent diffractive imaging (CDI). The latter comprises methods that exploit the coherence of X-ray synchrotron sources to replace imaging optics by reconstruction algorithms. Researchers from the Paul Scherrer Institut have recently demonstrated fast CDI image acquisition above 25,000 resolution elements per second using an in-house developed Eiger detector. This rate is state of the art for diffractive imaging and even on a par with the fastest scanning X-ray transmission instruments. High image throughput is of crucial importance for both materials and biological sciences for studies with representative population sampling.

Phase contrast improves mammography

Media Releases Medicine Human Health

Phase contrast X-ray imaging has enabled researchers at ETH Zurich, the Paul Scherrer Institute (PSI) and the Kantonsspital Baden to perform mammographic imaging that allows greater precision in the assessment of breast cancer and its precursors. The technique could improve biopsy diagnostics and follow-up.

X-rays film inside live flying insects – in 3D

Media Releases Biology Research Using Synchrotron Light User Experiments

Scientists have used a particle accelerator to obtain high-speed 3D X-ray visualizations of the flight muscles of flies. The team from Oxford University, Imperial College, and the Paul Scherrer Institute (PSI) developed a groundbreaking new CT scanning technique at the PSI’s Swiss Light Source to allow them to film inside live flying insects. The movies offer a glimpse into the inner workings of one of nature’s most complex mechanisms, showing that structural deformations are the key to understanding how a fly controls its wingbeat.

Observed live with x-ray laser: electricity controls magnetism

Media Releases Research Using Synchrotron Light Materials Research Matter and Material SwissFEL

Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.

X-ray tomography reaches 16 nm isotropic 3D resolution

Researchers at PSI reported a demonstration of X-ray tomography with an unmatched isotropic 3D resolution of 16 nm in Scientific Reports. The measurement was performed at the cSAXS beamline at the Swiss Light Source using a prototype instrument of the OMNY (tOMography Nano crYo) project. Whereas this prototype measures at room temperature and atmospheric pressure, the OMNY system, to be commissioned later this year, will provide a cryogenic sample environment in ultra-high vacuum without compromising imaging capabilities. The researchers believe that such a combination of advanced imaging with state-of-the-art instrumentation is a promising path to fill the resolution gap between electron microscopy and X-ray imaging, also in case of radiation-sensitive materials such as polymer structures and biological systems.

SwissFEL Undulator Prototype in the Injector Test facility - self-amplified spontaneous emission achieved

On December 5th, the 17 tons SwissFEL undulator prototype (In-vacuum Undulator U15) has been successfully moved from the Undulator lab (SLS) to the SwissFEL Injector Test Facility (SITF). The commissioning of the U15 prototype with electron beam is an important step to validate the U15 design and also to detect possible improvements before full series production. At first, the alignment procedure of the U15 segment with the electron beam has been tested. The test was extremely successful - the beginning of the SASE (self-amplified spontaneous emission) amplification could be seen last night. Please watch the short movie SASE.

International Year of Crystallography 2014 - Paul Scherrer Institut is IYCr Supporter

The International Year of Crystallography 2014 (IYCr2014) commemorates not only the centennial of X-ray diffraction, which allowed the detailed study of crystalline material, but also the 400th anniversary of Kepler’s observation in 1611 of the symmetrical form of ice crystals, which began the wider study of the role of symmetry in matter. Twenty two large-scale facilities, among them the SLS, sponsor the UNESCO/IUCr Open Labs and Summit Meetings initiatives during the International Year of Crystallography - see IYCr Supporter.

Super-volcano triggers recreated in X-ray laboratory

Scientists have reproduced conditions inside the magma chamber of a super-volcano to understand what it takes to trigger its explosion. These rare events represent the biggest natural catastrophes on Earth except for the impact of giant meteorites. Using synchrotron X-rays, the scientists established that super volcano eruptions may occur spontaneously, driven only by magma pressure without the need for an external trigger. The results are published in Nature Geoscience, online publication, January 2014.
