The world’s most powerful neutron microscope
Researchers from the Paul Scherrer Institute PSI in Villigen have delivered a key component for the ESTIA reflectometer at the European Spallation Source ESS based in Lund, Sweden. When it comes into service in 2026, ESS will be the world’s most powerful neutron source. Switzerland is making a vital contribution to the project. Scientists from across the globe will use ESS instruments to study processes and structures on the atomic scale, advancing materials research to a new level.

Young Scientist Award 2020
The Young Scientist Award 2020 of the European Magnetism Association (EMA) goes to Claire Donnelly for advances in the experimental characterization of spin textures and their dynamics in three dimensions with X-ray techniques.
Claire Donnelly, a former Ph.D. and postdoc at PSI in the Mesoscopic Systems Group, is currently a Leverhulme Early Career Research Fellow in the Cavendish Laboratory, University of Cambridge. She received her PhD in 2017 from the ETH Zurich for her work on hard X-ray tomography of three-dimensional magnetic structures based at the Paul Scherrer Institute. Following a postdoc at the ETH Zurich, she moved to the University of Cambridge and the Cavendish in January 2019, where she is focusing on the dynamics of three-dimensional magnetic nanostructures.
Her research focuses on three dimensional magnetic systems, which she studies using sophisticated synchorotron X-rays to determine the three-dimensional magnetic configurations, and their dynamic behaviour, at the nanoscale.
