Large Research Facilities Proton accelerator Spallation Neutron Source (SINQ) UCN Swiss Muon Source (SµS) 50% of the research at PSI is based on accelerators Synchrotron Light Source (SLS)
The protons are accelerated to 590 MeV (80% of the speed of light) and cover a distance of 4km. power = 590 MV ∙ 2.2 mA = 1.3 MW ≙ 1750 HP 2.2 mA ≙ protons/s The PSI Proton Accelerator Facility
