  It is shown that muon decays in straight sections of muon collider rings will
naturally produce highly collimated neutrino beams that can be several orders
of magnitude stronger than the beams at existing accelerators. We discuss
possible experimental setups and give a very brief overview of the physics
potential from such beamlines. Formulae are given for the neutrino event rates
at both short and long baseline neutrino experiments in these beams.
