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.

Puzzling new behaviour observed in high-temperature superconductors

Media Releases Matter and Material Materials Research Research Using Synchrotron Light

New effect might be important for emergence of High-Temperature Superconductivity
An international team of researchers has observed a new, unexpected kind of behaviour in copper-based high-temperature superconductors. Explaining the new phenomenon – an unexpected form of collective movement of the electrical charges in the material – poses a major challenge for the researchers. A success in explaining the phenomenon might be an important step toward understanding high-temperature superconductivity in general. The crucial experiments were conducted at the Paul Scherrer Institute.

A large scale research facility disappears in the woods

SwissFEL SwissFEL Construction

The building of the new PSI large-scale research facility SwissFEL in Würenlingen forest could only enjoy the sunshine for a brief spell: it is now disappearing under a mound of earth. This superstructure is one of the measures taken to integrate the facility as harmoniously as possible into the natural environment.

Useful for spintronics: Big surprises in a thin surface region

Media Releases Research Using Synchrotron Light Materials Research Matter and Material

The need for ever faster and more efficient electronic devices is growing rapidly, and thus the demand for new materials with new properties. Oxides, especially ones based on strontium titanate (SrTiO3), play an important role here. A collaborative project headed by scientists from the PSI has now revealed properties of strontium titanate that make it an important base material for applications in spintronics.

Neue Erneuerbare auf Integrationskurs

Energy and Environment

Die Energiestrategie 2050 des Bundes sieht einen starken Ausbau der neuen erneuerbaren Energien wie Solar- und Windenergie vor. Die Integration dieser dezentral und mit zeitlichen Schwankungen produzierten Energie stellt die Stromnetze vor eine grosse Herausforderung. Eine mögliche Lösung besteht darin, Stromüberschüsse, die die Netze überlasten würden, zur Herstellung energiereicher Gase wie Wasserstoff oder Methan zu nutzen. Das als Power-to-Gas bezeichnete Konzept steht im Mittelpunkt der neuen Energy System Integration-Plattform (ESI) am PSI.

Foundation Stone Ceremony Marks Scientific Importance of ESS

Large Research Facilities Research Using Neutrons

Today, several hundred members of the European scientific community gathered at the European Spallation Source (ESS) construction site in Lund, Sweden, for the ESS Foundation Stone Ceremony. The event was held to ‘lay the foundation’ both for the new facility, which has recently begun construction, and for a new generation of science in Europe.
