One thousand modules for CERN
At CERN near Geneva, tiny particles with extremely high energies are blasted at each other to answer big questions about the universe. The detectors that observe the collisions of these particles require regular upgrades. Lea Caminada and her High Energy Particle Physics research group at PSI play an important role in this quest.
Important funding for muon research
PSI gets an NCCR: The Muoniverse project will further expand research on the beamlines for elementary particles called muons – at the world’s leading facility for muon beams.
“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.

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.
