  We outline in detail a staging scenario for realizing the Neutrino Factory
and the Muon Collider. As a first stage we envisage building an intense proton
source that can be used to perform high intensity conventional neutrino beam
experiments ("Superbeams"). While this is in progress, we perform R&D in
collecting, cooling and accelerating muons which leads to the next two stages
of "Cold Muon Beams" and the Neutrino Factory. Further progress in Muon Cooling
especially in the area of emittance exchange will lead us to the Muon Collider.
A staged scenario such as this opens up new physics avenues at each step and
will provide a long range base program for particle physics.
