  The NuMI facility at Fermilab will provide an extremely intense beam of
neutrinos for the MINOS neutrino-oscillation experiment. The spacious and
fully-outfitted MINOS near detector hall will be the ideal venue for a
high-statistics, high-resolution $\nu$ and $\nubar$--nucleon/nucleus scattering
experiment. The experiment described here will measure neutrino cross-sections
and probe nuclear effects essential to present and future neutrino-oscillation
experiments. Moreover, with the high NuMI beam intensity, the experiment will
either initially address or significantly improve our knowledge of a wide
variety of neutrino physics topics of interest and importance to the
elementary-particle and nuclear-physics communities.
