Find out more about the research questions we are working on and the unique large-scale research facilities we are using to find answers.
Future technologies
New technologies are the driving force behind an innovative society. At PSI, researchers are laying the necessary foundations for this. They are looking for previously unknown ways of processing and storing data, making technologies more sustainable and efficient or developing new processes to delve ever deeper into the micro and nano worlds. Their findings form the basis for new applications - be it in medicine, information technology, energy generation and storage - or for new production processes in industry.
Peering into matter with ultrashort X-ray ripples
An all-X-ray transient grating experiment allows scientists to study the dynamics of quantum particles at the nanoscale.
Attorney for cutting-edge technology
Former PSI doctoral candidate Stephanie Smit now works as a patent attorney for a company that is among the most important in the world. That’s because this company builds machines that are worth a fortune and are highly sought after.
PSI research at Switzerland’s most-visited museum
Making energy research something visitors can experience: The Swiss Museum of Transport is creating a platform for political and social dialogue on energy issues.
Energy and Climate
Climate change is one of the greatest challenges of our time. Switzerland aims to be climate-neutral by 2050 – in other words, not to emit more greenhouse gases than can be absorbed naturally or by technical means. This calls on us to rethink our energy production and use – away from fossil fuels and towards climate-neutral energy sources. How can Switzerland become fit for a climate-neutral energy future? Researchers at PSI are looking for answers.
AI paves the way towards green cement
Researchers at PSI are using artificial intelligence to develop environmentally friendly formulations for cement.
Targeted funding of innovation for the energy transition
How do innovations arise and how can they be specifically encouraged for the energy transition? PSI researcher Michael Weinold has been looking into this question using LED lamps as an example.
A faster route to green hydrogen
The pH value determines how easily hydrogen can be produced from water when cobalt is used as a catalyst. PSI researchers have now found out why.
Health Innovation
New methods for diagnosis and therapy are at the centre of medical research and development at PSI. In cancer diagnosis, the focus is on early detection. Basic research using the latest methods leads to the development of innovative therapies. PSI works very closely with universities, clinics and the pharmaceutical industry.
Using terbium against lymphoma
Promising laboratory experiments at PSI show that radionuclide therapy with the radioactive element terbium could combat lymphoma effectively.
Using AI to identify genetic perturbations from cell images
New AI identifies genetic perturbations in chromatin – a potential approach in diagnostics and drug development.
Creating circuit diagrams of the brain
Using brain circuit diagrams to understand Alzheimer's.
Fundamentals of Nature
At PSI, researchers investigate the basic structures of matter and the fundamental principles of nature. They examine the smallest building blocks of matter or investigate the structure of biological molecules and how they perform their tasks. The knowledge gathered in this way opens up new approaches to finding solutions in science, medicine and technology.
New standards in nuclear physics
With unprecedented precision: PSI researchers measure the nuclear radius of muonic helium-3 and put the theories of atomic physics to the test.
With pad, pencil, and algorithms
Physicist Dominik Sidler is developing fundamental theories for previously inexplicable phenomena.
Prestigious funding for research at PSI
Concrete, chemical catalysis and the search for new physics – three PSI researchers have each received a grant from the Swiss National Science Foundation for these areas of research.
Our large research facilities
PSI develops, builds and operates complex large research facilities. PSI has the world's most powerful muon source, a unique proton and neutron source, an synchrotron of international importance and one of only five X-ray free-electron lasers with hard X-rays in the world. Scientists from all over the world use PSI's large research facilities for their scientific investigations. They are also available to Swiss research and industry for their experiments.
World record attosecond measurement at SwissFEL
Scientists at SwissFEL can measure X-ray pulses with attosecond time resolution.
A tiny golden object from Roman times
PSI’s David Mannes has used neutrons to unravel the mystery of a fascinating archaeological artefact.
SLS 2.0: How to start up a particle accelerator
The electrons are back: after its upgrade, the Swiss Light Source SLS is starting up again, step by step.
