The MINOS detector will study neutrino (mostly nu_mu) beams from
the NuMI beam facility at FermiLab. The base-line is 730 km. The 5 Ktom
iron calorimeter detector with scintillator detector will detect both nu_mu
as well as nu_e and so can study the reappearance of nu_mu as well as
oscillations into nu_e directly. If no oscillations are seen, limit
plots will show the sensitivity to the mixing parameters; if oscillations
are seen, then the measurements will yield precision values for some of
the mixing parameters. The NuMI beam is expected to be operational by
Dec 2004. All plots are for 10 Kton year of data; i.e., two years of
running with beam. Greatest sensitivity is with lowest energy beam. For
more details, look up the MINOS (NuMI) web-site at

discrimination in the plots for me and he.
nu_mu to nu_e ; delta_23 = 3.10^-3, delta_12
= 10^-5, \theta_13 = 8 degrees; delta_CP = 120 degrees (for matter
effect).

nu_mu -> nu_s. f_s = 1 - sin^2 (2 \theta_23). f_s = 0 implies pure
active, f_s = 1 means pure sterile transformation.
