Wir schaffen Wissen – heute für morgen

The Paul Scherrer Institute, PSI, is the largest research institute 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.

En route to better transformers

Media Releases Matter and Material Research Using Neutrons

Thanks to an ultramodern research method, scientists have successfully looked inside transformers and observed the magnetic domains at work in the interior of a transformer’s iron core. Transformers are indispensable in regulating electricity both in industry and in domestic households. The current research results show that the new examination method can be profitably applied to develop more efficient transformers.
