Research Using Synchrotron Light

The X-ray free-electron laser SwissFEL really is as high-performance and versatile as planned.

Switzerland plans to construct a deep repository for its radioactive waste. There are three potential locations, and data obtained by PSI researchers can aid in selection of the best one.

In our bodies, G protein-coupled receptors mediate countless processes. PSI researcher Ramon Guixà talks about how he brings those receptor molecules to life on the computer screen.

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.

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.

It is necessary to prepare now for the planned upgrade of the Swiss Light Source SLS. In order to do justice to future research, Alun Ashton is estimating the amount of data that future experiments will produce.

Measurements at the Swiss Light Source SLS have helped to understand how the only known natural protein-mineral crystal is formed. It is part of the fascinating glass skeleton of sponges.

At PSI, researchers decipher the structure of the proteins in bacteria and viruses. This knowledge can aid, for example, in the development of drugs against infectious diseases. But before the investigation can begin, an extremely tricky problem has to be solved: the crystallisation of the molecules.

PSI congratulates Emmanuelle Charpentier and Jennifer Doudna on winning this year's Nobel Prize in Chemistry. Experiments at the Swiss Light Source SLS in 2013 made it possible to elucidate the structure of the protein complex CRISPR-Cas9.

PSI scientists have investigated a material that could be suitable for future data storage applications. They have manipulated the crystalline structure of their sample while measuring how this affects the material’s magnetic and electronic properties.

Zeolites are already indispensable additives in the chemical industry – researchers from PSI and ETH Zurich suggest ways to make them still more efficient.

At PSI, researchers are screening molecule fragments to see if these bind to important proteins of the coronavirus SARS-CoV-2 and thus have the potential to disable it. They are hoping the many individual pieces of information will yield an answer as to what an effective drug might look like.

The Swiss Light Source SLS is set to get an upgrade to make excellent research possible in the coming decades as well. Hans Braun, SLS 2.0 project leader, talks about this undertaking in an interview.

Frankfurt scientists identify a possible weakness of the SARS-CoV-2 virus. They carried out part of their measurements at PSI's Swiss Light Source SLS. The research results are published this week in the scientific journal Nature.

At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). This new understanding at the atomic level will help to develop new lighting materials that have higher light output and also are cost-efficient to manufacture.

Tomographic images from the interior of fossils, brain cells, or computer chips are yielding new insights into the finest of structures. These 3-D images are made possible by the X-ray beams of the Swiss Light Source SLS, together with detectors and sophisticated computer algorithms developed at PSI.

Using a newly developed imaging method, researchers were able to visualise the magnetic structure inside a material with nanoscale resolution. They succeeded in creating a short "film" consisting of seven movie frames that shows, for the first time in 3D, how tiny vortices of the magnetisation deep within a material change over time.

The Swiss Light Source SLS is set to undergo an upgrade in the coming years: SLS 2.0. The renovation is made possible by the latest technologies and will create a large research facility that will meet the needs of researchers for decades to come.

Researchers at the Paul Scherrer Institute PSI have developed a new process with which fibre-reinforced composite materials can be precisely X-rayed. This could help to develop better materials with novel properties.

The newest large research facility at the Paul Scherrer Institute, SwissFEL, has been completed. In January 2019 it began regular operation. Henrik Lemke, head of the SwissFEL Bernina research group, gives an interim report.
