  1. Status of the BooNE Experiment Les Recontres de Physique de la Vallée d’Aoste La Thuile, Italy March 5, 2001 Randy Johnson University of Cincinnati for the BooNE Collaboration BooNE Status

  2. Mass range accessible to moderate accelerator experiments Neutrino Oscillation Masses Three different types of experiments – three different mass ranges! BooNE Status

  3. The Problem LSND Sees a Signal Karmen 2 Does Not BooNE Status

  4. Still very clearly an “allowed” region Are They Really in Conflict? NOT YET!!! BooNE Status

  5. The Solution Need a Definitive Experiment Must cover LSND/Karmen 2 region with >5 sigma sensitivity Will need very high neutrino flux and extremely good control of backgrounds BooNE Status

  6. BooNE FNAL – E898 Booster Neutrino Experiment • Similar L/E as LSND, L and E are 10x LSND • Different neutrino production process from LSND • Similar particle identification as Super K • Completely different systematic errors and backgrounds BooNE Status

  8. BooNE Design of a Neutrino Experiment • Beam • High intensity proton beam • 5x1020 POT at 8 GeV/c from Booster • Secondary focusing system • Long decay volume • 50 m decay pipe • Large Detector • 800 tons Mineral Oil • 1280 8” PMTs in active region • 240 PMTs in outer veto region Bartosek Engineering 6 ft BooNE Status

  9. BooNE The Neutrino Flux • High purity muon neutrinos • Flux peaked at about 1 GeV • Major electron neutrino sources: • Muon decay • Kaon decays BooNE Status

  10. BooNE Electron Neutrino Backgrounds Target and Horn Dump BooNE Status

  11. BooNE Controlling Beam Systematics 1) Particle Production – Multiple dumps Removable dump at 25 m Signal from: ~1/2 Backgrounds from: ~1/4 Unaffected BooNE Status

  12. BooNE Controlling Beam Systematics 2) Particle Production – Kaons Little Muon Counters Measure kaon production through measuring high pt muons BooNE Status

  13. BooNE Controlling Beam Systematics 3) Beam Steering Downstream muon monitors (ionization chambers) installed in beam dump BooNE Status
