Secondary beam lines at PSI
PSI provides beam time for particle physics and other experiments. Its unique specialty is very high intensity pion and muon beams of momenta up to a few hundred MeV/c as well as ultracold neutrons. The secondary beam lines are maintained jointly by the Laboratory for Particle Physics, the Division of Large Research Facilities and the Spallation Source Operation Group.
