  1. Booster Neutrino Experiment(BooNE) About Neutrinos The BooNE Project

  2. Neutrino Mysteries • Dark matter in the universe, galactic dynamics • Supernova explosions, do they produce the element abundance seen in the universe? • Solar physics, our only view into the core of the sun • To answer the above we need to know more about neutrinos: do they have mass? Do they mix? Are there only three states?

  3. My abbreviated version of neutrino history… • 1914: Chadwick finds  decay spectrum to be continuous • 1930: W. Pauli proposed ‘neutron’ as an explanation • 1936: Fermi-Gamow-Teller theory with a “neutrino” • 1956: Cowan and Reines observe einteractions • 1990: Precisely 3 light neutrinos exist in nature (SLC/LEP) • 1997: LSND observes neutrino flavor oscillation effect • 2000: DONUT collaboration observes interactions

  4. BooNE Experiment • Confirm and Measure LSND Neutrino Oscillation Effect

  5. MiniBooNE Project • Purpose: Verify observations at Los Alamos of neutrino oscillations (LSND) • Supporting Organizations: DOE/ER/HEP, DOE/ER/NP, Los Alamos • Location: Fermi National Laboratory • Cost: ~ 18 M$

  8. MiniBooNE Neutrino Source

  9. Proton Target Assembly • Primary 8 GeV proton beam: • 5x1012 protons @ 5 Hz • 600 W power load 65-80 cm Gas Cooled Beryllium Target

  10. Horn Focused Pion Beam • The Design: • 170 kA, 5 Hz (average), 200M pulses/year Charged pions and kaons are focused toward the detector with a single horn. 8 GeV protons Target is inside the inner conductor of horn

  11. MiniBooNE Detector Tank • Pure mineral oil throughout • 807 tons total, 445 tons mineral oil • 1280 phototubes in the detector region • 240 phototubes in the veto region.

  12. MiniBooNE Schedule • Civil construction started mid-1999 and will finish October 2000 • Beam line construction started mid 2000 and is scheduled to finish summer 2001 • Operation scheduled to start December 2001 • If LSND signal is observed, second detector construction is scheduled for ~2003
