摘要：

We consider the parameters of an entry-level neutrino factory designed to make the first observation of nu(e) --> nu(mu) oscillations, measure the corresponding amplitude sin(2)2 theta(13), and determine the sign of the atmospheric-scale delta m(32)(2) via matter effects. A 50 kt detector, a stored muon energy E(mu)greater than or equal to 20 GeV and 10(19) moon decays would enable these goals to be met provided sin(2)2 theta(13)>0.01. The determination of the sign of delta m(32)(2) also requires a baseline L greater than or equal to 2000 km. An upgraded neutrino factory with O(10(20)) decays would enable the first observation of nu(e) --> nu(tau) oscillations. With O(10(21)) decays the effects of a large CP phase could be measured in the case of the large angle matter oscillation solution to the solar neutrino anomaly. Our analysis includes a family of three-neutrino models that can account for the atmospheric and solar neutrino oscillation indications.
