The PSI Laboratory of Particle Physics pursues fundamental research, addressing up to date questions in modern, accelerator-based particle physics.
Lab News and Scientific Highlights
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.
Muons receive funding from the Swiss National Science Foundation
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.
ERC Consolidator Grant for Neutron Lifetime Experiment at PSI’s source for ultracold neutrons
Our collaborator Prof. Dr. Martin Fertl from the Johannes Gutenberg University Mainz (JGU) and the PRISMA+ Cluster of Excellence has been awarded an ERC Consolidator Grant, one of the EU's most highly endowed grants, to support the development of the next-generation neutron lifetime experiment.
