Neutrino KB01 Program Four-Year Research Plan 2006 – Present first neutrino oscillation results from the MiniBooNE experiment in the summer and take data with antineutrinos – Continue taking data with antineutrinos. If MiniBooNE confirms the LSND evidence for neutrino oscillations*, write proposals for follow-up experiments at Fermilab (BooNE) & ORNL (OscSNS) – Present first antineutrino oscillation results. Continue taking data with antineutrinos and obtain approval and funding for follow-up experiments at Fermilab (BooNE) & ORNL (OscSNS) Continue taking data with antineutrinos and begin construction for follow-up experiments at Fermilab (BooNE) & ORNL (OscSNS) Continue taking data with antineutrinos and complete construction for follow-up experiments at Fermilab (BooNE) & ORNL (OscSNS). * If MiniBooNE does not confirm LSND => Join Majorana Double-  Decay Experiment

MiniBooNE Highlights MiniBooNE has collected ~750K neutrino events from ~7E20 Protons on Target Experiment is working well (>99% livetime & 99% of PMT channels working well) Clearly reconstructing CCQE, CCPI+, NCPI0, & NCEL events First focussing horn was replaced during 2004 fall shutdown! First horn set a world record of 96M pulses (previous record set at BNL with 13M pulses) Now taking data with Antineutrinos
