  3. Target for muon collider

  4. MERIT experiment • The MERIT experiment, to be run at CERN in 2007, is a proof-of-principle test for a target system that converts a 4-MW proton beam into a high-intensity muon beam for either a neutrino factory complex or a muon collider. The target system is based on a free mercury jet that intercepts an intense proton beam inside a 15-T solenoidal magnetic. The Hg jet delivery system will generate a 1-cm diameter mercury stream with velocities up to 20 m/s.
