  We review the physics potential for experiments with intense neutrino beams
at the front-end of a muon storage ring, stressing the way the spin and flavour
structure of neutrino interactions with matter can be used to shed light on the
structure of the strong and electroweak interactions. Specifically, we discuss
precision tests of the standard model, studies of polarized and unpolarized
structure functions of the nucleon, and several new and exotic physics items.
