The MiniBooNE detector

The MiniBooNE neutrino detector was designed and built to look for νμ→νeνμ→νe oscillations in the (sin22θ,Δm2) parameter space region where the LSND experiment reported a signal. The MiniBooNE experiment used a beam energy and baseline that were an order of magnitude larger than those of LSND so that the backgrounds and systematic errors would be completely different. This paper provides a detailed description of the design, function, and performance of the MiniBooNE detector.
