“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.

Where analysis meets flavours
Some see brewing as an art, others as a science – Luc Van Loon combines both these virtues at his brewery. With the nose of a sommelier and the precision of a chemist, the former PSI researcher creates world-class beers.
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.
