The neutrino activity would permit a comprehensive neutrino science program over a decade or more that would include the precision measurement of neutrino mass differences and oscillation parameters, plus very possibly the measurement of matter-antimatter asymmetries (CP violation) that could connect the neutrino sector to leptogenesis as a source of the matter-antimatter asymmetry of the universe.

The Neutrinos at the Main Injector (NuMI) beam is the most powerful neutrino beam that has ever operated, with up to 0.3 MW of proton beam power directed at the NuMI target. The Main Injector Neutrino Oscillation Search (MINOS) collaboration operates two detectors, one at a distance of 730 km in the Soudan mine which are necessary to disentangle the effects of neutrino interactions with matter from the possible effects of CP violation. The sensitivity of an experiment is proportional to (beam power) x (detector mass) x (detector efficiency). Fermilab is increasing the NuMI beam intensity through a series of steps to a total beam power of 0.4 MW on target by 2010. The primary modifications to the complex include conversion of the Recycler Ring from an antiproton storage ring to a proton accumulator ring, and the conversion of the Antiproton Accumulator ring to a proton momentum stacking ring. Such conversions would allow Fermilab to continue operations of the neutrino program at the forefront of the field through the middle-to-end of the next decade. In parallel we continue to pursue a modest R&D program aimed at developing highly efficient techniques for very high intensity proton acceleration based on superconducting rf technologies. Such technologies could provide a basis for further long term performance enhancements if called for.
