Paul Scherrer Institute

The Paul Scherrer Institute, PSI, is the largest research centre for natural and engineering sciences within Switzerland. We perform world-class research in three main subject areas: Matter and Material; Energy and the Environment; and Human Health. By conducting fundamental and applied research, we work on long-term solutions for major challenges facing society, industry and science.

Seven nanometres for the electronics of the future

Micro- and Nanotechnology Materials Research Matter and Material

Researchers from the Paul Scherrer Institute have succeeded in creating regular patterns in a semiconductor material that are sixteen times smaller than in today’s computer chips. As a result, they have taken an important step closer towards even smaller computer components. Industry envisages structures on this scale as the standard for the year 2028.

Particulate matter from modern gasoline engines damages our lungs

Media Releases Environment Energy and Environment

For years, studies have proved that fine dust from petrol engines can damage our health. Modern engine technology does not help, either, as researchers from the University of Bern and the Paul Scherrer Institute (PSI) reveal.

Together, not alone

Research Using Synchrotron Light SwissFEL Experiments Human Health

Decoding biomolecules at SwissFEL and SLS
Proteins are a coveted but stubborn research object. A method developed for x-ray free-electron lasers and PSI’s future SwissFEL should now help researchers to make good headway in this field. It involves x-raying many small, identical protein samples consecutively at short intervals, thereby avoiding the main problem that protein research has faced thus far: producing samples in a sufficient size.

First undulators reach the SwissFEL building

SwissFEL SwissFEL Technology SwissFEL Construction

The first undulator frames have arrived at the SwissFEL building. They will take around six months to assemble, after which the finished undulators will be taken to the SwissFEL accelerator tunnel for installation.

From inside an eggshell

Research Using Synchrotron Light Large Research Facilities

Tiny cavities inside eggshells supply the materials that stimulate and control the shell’s growth. Using a novel imaging technique, researchers from the Paul Scherrer Institute (PSI), ETH Zurich and the Dutch FOM Institute AMOLF have succeeded in depicting these voids in 3D for the first time. In doing so, they lift an old limitation of tomographic images and hope that one day medicine will also benefit from their method.
