Swiss Spallation Neutron Source (SINQ)

The spallation neutron source SINQ is a continuous source - the first of its kind in the world - with a flux of about 1014 n/cm2/s. Beside thermal neutrons, a cold moderator of liquid deuterium (cold source) slows neutrons down and shifts their spectrum to lower energies. These neutrons have proved to be particularly valuable in materials research and in the investigation of biological substances. SINQ is a user facility. Interested groups can apply for beamtime on the various instruments by using the SINQ proposal system.

Swiss Muon Source (SµS)

The Swiss muon source – powered by the PSI 590 MeV cyclotron with a proton current of 2200 μA is the world's most intense continuous beam muon source. The proton beam hits two graphite targets. Attached to those are seven beamlines for muon (or pion) extraction, two of them are equipped with superconducting decay channels. The available muon energies range from 0.5 keV to 60 MeV. The main advantage of continuous muon beams is the detection of individual muons by fast-timing scintillation counters, easily providing nanosecond or better time resolution of the muon response.

Particle Physics (PP)

At the particle physics facilities at PSI fundamental research is performed, addressing the most up to date questions in modern physics. The results enable a better understanding of the fundamental building-blocks of nature as well as the forces acting on them. In collaboration with researchers from both Switzerland and abroad we utilize the world's most intense sources of low-energy pions and muons at PSI and in the near future also of ultra-cold neutrons. Our specialized knowledge of detector design and construction, electronics and chip design is widely applied both in our experiments at PSI and in the CMS experiment at CERN, as well as in other applications and spin-offs from the field of particle physics at PSI and world-wide.
