NuMI will deliver an intense muon neutrino beam of variable energy 2-20 GeV directed into the Earth at 58 mrad for short (~1 km) and long (~700-900 km) baseline experiments. Several aspects of the design are reviewed, as are potential upgrade requirements to the facility in the event a Proton Driver is built at Fermilab to enhance the neutrino flux.Paper given at the ICFA Workshop on High Intensity Hadron Beams (HB2004), Bensheim, Germany, 18-22 October, 2004High Energy Physics - Experimenttext
