Survey and alignment of the Fermilab MiniBooNE horn and target

The first phase of the BooNE (Booster Neutrino Experiment) program at Fermilab is called MiniBooNE. One of the primary goals is to test for neutrino mass via a search for neutrino oscillations. The MiniBooNE consists of a Neutrino Beam and a 40-foot (12.2-meter) diameter Detector. The detector is located 500 m from the neutrino beam line fed by the 8 GeV protons Booster. The Neutrino Beam consists of four sections: the Target, the Horn (focusing system), the decay region, and the beam absorber. This paper discusses the alignment methodology employed to survey the MiniBooNE Horn and Target.
