We create knowledge – today for tomorrow

The scientific topics being researched at the Paul Scherrer Institute can be summarised in three main fields: Matter and Material, Energy and the Environment, and Human Health. Researchers working on Matter and Materials at PSI explore the properties of a wide variety of materials by identifying how they are made up of small particles inside and how this structure defines the properties of the material. Understanding essential processes in living organisms at the molecular level and developing new methods for diagnosing and treating diseases are the goals of research in the field of Human Health. The Centre for Proton Therapy at PSI treats patients suffering from cancer. The aim of Energy Research at PSI is to develop technologies for sustainable energy use. This includes environmentally friendly energy production, the utilisation of renewable energy sources and low-loss energy storage. PSI also makes new research findings accessible to industry. Swiss companies can thus convert research into innovation.

Visiting scientists

Around 2'400 researchers from all over the world visit us every year.

The large research facilities at PSI are unique

PSI operates several large research facilities where experiments are carried out that are not possible in smaller laboratories. These large research facilities are unique in Switzerland. At the Swiss Light Source (SLS) researchers "illuminate" a wide variety of materials with synchrotron light. This enables them to determine the detailed composition of even the smallest structures down to nano size. The ultra-short X-ray laser pulses of the X-ray free-electron laser SwissFEL, the latest research facility, turn processes in the smallest detail into films: they enable researchers to observe ultra-fast processes.

At the Swiss Spallation Neutron Source SINQ, neutron beams are used to investigate new materials, e.g. for superconductors or computer memories, but also to examine metals so that one can look inside an engine or a bronze bust. At the Muon Source SμS at PSI, muons are mainly used to determine magnetic fields inside materials. Our research facilities with a unique infrastructure, combined with the technical skills within our manufacturing workshops and our specialists' knowledge, make PSI a sustainable partner in research and industry.

Equal Opportunities and Diversity

At PSI we live diversity and see diversity as a value. We are proud that people from different backgrounds and with different skills work together on our campus with the necessary mutual respect. As a federal institution we are aware of our social responsibility and act in an exemplary manner in terms of equal opportunities and inclusion. We are proud to have been awarded the label Friendly Work Space. In order to maintain this claim, we invest in a respectful work culture without stereotypes and prejudices.

We cultivate and promote a culture of continuing education among all employees and managers. We support the topic of compatibility of family and career with various support programmes. In vocational training in particular, we want to increasingly promote the recruitment of people with disabilities. We want to fill more positions with women, and to this end we invest specifically in the career advancement of women. At PSI, we live diversity and claim to be known and recognised for a serious inclusion policy.

With the Diversity Award for managers PSI honours the promotion of equal opportunities.

Vindonissa

Vindonissa, located in what is today called Windisch, was an important Roman legion's camp. The ruins of the camp are open for viewing. The monastery church of Königsfelden, which is well known for its unique glass windows (that date back to the 14th century), is located in the middle of these ruins.
