New 6M€ European grant awarded to ExPaNDS to drive open access data
A new 6M€ grant is being launched for the Photon and Neutron Data Services (ExPaNDS) to come together and work under the European Open Science Cloud (EOSC). This ambitious project will create enormous opportunities for scientific communities, and through their findings for humankind worldwide. It aims to publish and map the data behind the thousands of successful published scientific papers generated by Europe’s Photon and Neutron Research Infrastructures (PaN RIs) – which every year create petabytes of data – and make it available to all.
Research and tinkering – SwissFEL in 2019
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.
Preventing tumour metastasis
Researchers at the Paul Scherrer Institute PSI, together with colleagues from the pharmaceutical company F. Hoffmann-La Roche AG, have taken an important step towards the development of an active substance against the metastasis of certain cancers. Using the Swiss Light Source SLS, they deciphered the structure of a receptor that plays a crucial role in the migration of cancer cells.
Observing solid-state batteries during deformation
PSI researchers have observed mechanical processes in solid-state batteries with unprecedented precision. Using X-ray tomography at the Swiss Light Source SLS, they discovered how fissures inside the batteries propagate. These insights can help to make batteries for electric cars or smartphones safer and more efficient.
Weyl fermions discovered in another class of materials
A particular variety of particles, the so-called Weyl fermions, had previously only been detected in certain non-magnetic materials. But now researchers at PSI have experimentally proved their existence for the first time in a specific paramagnetic material.
Molecular energy machine as a movie star
Using the Swiss Light Source SLS, PSI researchers have recorded a molecular energy machine in action and thus revealed how energy production at cell membranes works. For this purpose, they developed a new investigative method that could make the analysis of cellular processes significantly more effective than before.
First demonstration of a Germanium laser
Scientist at the Paul Scherrer Institut and ETH Zürich, with colleagues from CEA Grenoble, have demonstrated and characterized a technology that, for the first time, yields lasing from strained elemental Germanium. This achievement underlines PSI’s leading role in the development of Silicon-compatible laser light sources.
PSI School for Master Degree Students - Introducing Photons, Neutrons and Muons for Condensed Matter Physics and Materials Science
From 17 – 21 June 2019 the Neutron and Muon Division (NUM) and the Photon Science Division (PSD) of PSI hosted 18 Master Degree students of physics, chemistry, materials and interdisciplinary science, as well as nuclear engineering to provide an introduction to the characterization of materials with large scale facilities like SINQ, SμS, SLS and SwissFEL. The course taught a basic understanding of how photons, neutrons and muons interact with matter, and how this knowledge can be used to solve specific problems in materials research.

First serial femtosecond crystallography experiment using SwissFEL’s large bandwidth X-ray pulses
The typical mode of operation at XFEL facilities uses the so-called self-amplified spontaneous emission (SASE) process to generate the short, bright X-ray pulses. This mode of operation is stochastic in nature, causing some variance in intensity and spectrum on a shot-to-shot basis, which makes certain types of crystallographic measurements much more challenging.
