Design concepts for a muon storage ring neutrino source

We described a preliminary design study for a muon storage ring neutrino source that could be built as a step towards the first muon collider. In our design the neutrino beam is produced by 3×1020 muon decays per year occurring within the straight section of a muon storage ring, and that intensity could be increased by upgrading the proton source intensity. The resulting neutrino flux is sufficient to produce hundreds of charged current interactions per year in a reasonable sized detector on the other side of the Earth.
