MiniBooNE began its two-year data collection run in August 2002. MiniBooNE's search for the oscillation of muon neutrinos into electron neutrinos will test the results of an earlier experiment, the Liquid Scintillator Neutrino Detector (LSND) experiment at the Los Alamos National Laboratory in New Mexico. LSND was the first experiment to report an appearance of electron neutrinos from a muon neutrino source.
MiniBooNE will search for neutrino oscillations with parameters in and around the region in which LSND reports a signal. Finding oscillations would further our understanding of the LSND result and enable the parameters of this sort of oscillation to be more precisely determined. If no oscillations are observed, MiniBooNE will extend the excluded region for neutrino oscillations.
