“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.
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.
X-raying auditory ossicles – a new technique reveals structures in record time
Using a bone, PSI researchers have demonstrated how the structures of biological materials can be determined on scales from nanometres to millimetres in a very short time.

Engineering skill and perseverance
Credit for the on-time completion of the major SLS 2.0 upgrade project is due in part to a team of dedicated electrical engineers.
PSI’s cement whisperer
John Provis has dedicated his research career to a building material that is far more exciting than you might think.
Creating circuit diagrams of the brain
Adrian Wanner aims to map the brain’s architecture. Doing this will allow us to better understand neurodegenerative diseases like Alzheimer’s.
