Fascinating research, or what are they actually doing there?

In these pages, we would like to present the Paul Scherrer Institute to an interested public in a generally comprehensible way. Here you can learn more about the research topics we are working on and the unique large research facilities we are using to find answers to a variety of scientific questions.

Diving into magnets

Media Releases Materials Research Matter and Material Research Using Synchrotron Light

For the first time, scientists have made visible the directions of the magnetisation inside a 3D magnetic object. The smallest details in their visualisation were ten thousand times smaller than a millimetre. Among others, the magnetic structure contained one outstanding kind of pattern: magnetic singularities called Bloch points, which up to now were only known in theory.

Nanomaterial helps store solar energy: efficiently and inexpensively

Media Releases Storage Energy and Environment Renewable Energies ESI Platform Materials Research

Efficient electrolysers are needed in order to store sun and wind energy in the form of hydrogen. Thanks to a new material developed by researchers at the Paul Scherrer Institute PSI and Empa, these devices are likely to become less costly and more efficient in the future. Researchers were also able to demonstrate that this new material can be reliably produced in large quantities, showing its performance capability in an electrolysis cell—the main component of an electrolyser.

Research experience from California benefits Swiss X-ray free-electron laser SwissFEL

Media Releases SwissFEL Matter and Material

An X-ray free-electron laser (XFEL) is capable of visualizing extremely fast structural and electronic processes. Pilot experiments will take place at the PSI's Swiss Free-Electron Laser (SwissFEL) from the end of 2017 on. Two current publications in Science and Nature Communications demonstrate the kind of outstanding scientific work that is enabled by such facilities. The work was carried out at the Linac Coherent Light Source (LCLS) in California. Two of the leading authors behind these studies have now relocated to the PSI in order to share their expertise as SwissFEL expands its capabilities.

Fuel and chemicals from plant waste

Media Releases Research Using Synchrotron Light Materials Research Matter and Material Energy and Environment

Lignin, as a constituent of many plants, accumulates in large quantities and could theoretically be used as a precursor material for production of fuels and chemicals. Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a method with which the processes that take place in the catalytic breakdown of lignin can be observed in detail. The knowledge thus gained could enable targeted improvement of production methods in the future.

Injector 2: a pre-accelerator for protons

Large Research Facilities

As fundamental building blocks of matter, protons are part of all the things that surround us. At the Paul Scherrer Institute PSI, though, they step out of their usual role and are deployed to generate other particles, namely neutrons and muons, which are then used to study materials. But for that, the protons first have to be accelerated. An important role in this is played by a three-stage accelerator facility, in the middle of which stands the accelerator known as Injector 2.

From the garage to the world

Research Using Neutrons

In 1999, PSI researchers founded the spin-off firm SwissNeutronics. Today the company has a staff of 15, sells high-precision components to research institutions all over the world, and still is based in the small town of Klingnau – not far from PSI.

Big help for small children

Human Health Medical Science

When small children develop cancer, the whole family is affected. Staff at the Paul Scherrer Institute PSI’s Centre for Proton Therapy combine target-oriented proton beam irradiation and a caring, warm-hearted atmosphere to help these children.

Quartz powder for the battery of the future

Media Releases Energy and Environment Materials Research

PSI materials researchers have developed a method that provides crucial insights into the charging and discharging processes of lithium-sulphur batteries. And the method revealed: with quartz powder added to the battery, its available energy increases and the gradual loss of capacity is much weaker.

Making a valuable resource usable with water

Media Releases Energy and Environment Research Using Synchrotron Light

In oil extraction sites, gaseous methane is simply burned, even though it could actually be a useful precursor material for fuels and products of the chemical industry. One way to make methane usable is to convert it to methanol. Researchers at the Paul Scherrer Institute PSI and ETH Zurich have now developed a new chemical process that allows this conversion in an efficient and inexpensive way.

Getting a Handle on Safety

Medical Science Human Health

Proton beams don’t just cure cancer. They can also damage healthy tissue. To make sure that this doesn’t happen, PSI’s Centre for Proton Therapy carries out over 350 safety tests a year. The results speak for themselves: several thousand patients have undergone proton irradiation treatment here in Villigen. There’s never been an accident.

Successful for 20 years: Probing materials with particles

Media Releases Matter and Material Research Using Neutrons Large Research Facilities

Whether they study materials for the electronics of the future, batteries, or swords from the Bronze Age — for 20 years researchers from a range of disciplines have been using the Swiss Spallation Neutron Source SINQ of the Paul Scherrer Institute PSI for their investigations. At a symposium on 18 April, researchers looked back on the facility's successes and presented plans for modernisation.

The double agents


They have two e-mail addresses, two offices, and two filing cabinets in two locations: Around 60 of the researchers at PSI are at the same time professors or lecturers at a Swiss university. PSI and the universities also profit from these researchers with double affiliations.

Second beamline for SwissFEL

SwissFEL SwissFEL Technology SwissFEL Experiments

This year the first pilot experiments are starting at the free-electron X-ray laser SwissFEL. The X-ray light generated by SwissFEL will enable a broad spectrum of experiments. Beginning in 2020, a second beamline will provide for a still greater variety.

3-D X-ray imaging makes the finest details of a computer chip visible

Media Releases Materials Research Micro- and Nanotechnology Matter and Material Research Using Synchrotron Light

Researchers at the PSI have made detailed 3-D X-ray images of a commercially available computer chip. In their experiment, they examined a small piece that they had cut out of the chip beforehand. This sample remained undamaged throughout the measurement. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications. Thus these results represent one important application of an X-ray tomography method that the PSI researchers have been developing for several years.
Older news can be found in the overview of the current year.
