News & Stories from PSI
“We’re pulling out all the stops”
PSI is increasing the intensity of its muon beams a hundredfold. This opens up entirely new possibilities for physics and materials research.
Identifying the sources of Sarajevo’s smog
Fumes from wood and coal burning as well as from cooking are the main sources of the heavy smog in the capital of Bosnia and Herzegovina. That’s the finding of a comprehensive mobile measurement campaign by PSI researchers.
A comprehensive energy system model for Switzerland
Energy systems face complicated, long-term challenges with a high degree of uncertainty. To explore these challenges and support decision-making, the STEM energy systems model from the Energy Economics Group at PSI has become a key tool.
Swiss X-ray laser reveals the hidden dance of electrons
New X-ray technique at SwissFEL shows how electrons act together – with the potential to show why quantum information slips so easily away.
