The NUM division performs world-class research with neutrons and muons to explore and understand matter and materials. The NUM division operates and develops the Swiss Spallation Neutron Source SINQ, the Ultra-cold Neutron Source UCN, the Swiss Muon Source SμS and the facilities for particle physics at the Paul Scherrer Institute and is one of the five PSI research divisions.
On June 25 the League of Advanced European Neutron Source LENS organized a second webinar on "New Directions in Instrumentation". Artur Glavic (LIN) gave a presentation on "Neutrons for Magnetic Nanostructures on Surfaces: Beyond the Specular Intensity Wars", which is still available online.
Perovskite oxynitride materials can act as effective photocatalysts for water splitting driven by visible light. A combined neutron and x-ray study now provides unique insight into the underlying processes at the solid–liquid interface and highlights how solar-to-hydrogen conversion can be improved.
Exotic atoms, in which electrons are replaced by other particles, allow deep insights into the quantum world. After eight years, an international group of scientists have succeeded in a challenging experiment conducted at PSI’s pion source: they created an artificial atom called “pionic helium”.
The first application of stroboscopic neutron diffraction to studying lithium-ion batteries during operation establishes a new approach to unravelling the complex processes playing out in energy-storage materials.
The new director of the Paul Scherrer Institute has taken up office today. Christian Rüegg aims to further reinforce the leading role of PSI's large research facilities, and thus promote Switzerland as a location for research.
