  Because muons connect directly to a standard-model Higgs particle in
s-channel production, a muon collider would be an ideal device for precision
measurement of the mass and width of a Higgs-like particle, and for further
exploration of its production and decay properties. Parameters of a
high-precision muon collider are presented and the necessary components and
performance are described. An important advantage of the muon collider approach
is that the spin precession of the muons will enable energy measurements at
extremely high accuracy (dE/E to 10-6 or better). The collider could be a first
step toward a high-luminosity multi-TeV lepton collider, and extensions toward
a higher-energy higher-luminosity device are also discussed.
