  1. SciBar at FNAL Booster Neutrino Beam Line T. Nakaya (Kyoto Univ.)

  2. MiniBooNE beamline SciBar Decay region MiniBooNE Detector 25 m SciBar (Fiducial:10t) 50 m 450 m 4m 3m n 3.5m MRD 3m 1.7m Ecal (11X0) 1m Experimental setup • 100m from the target • On-axis position • (1~2)x1019 POT/month • Bring SciBar detector to FNAL • (including readout electronics) • Arrange MRD (Iron plates + Scinti.) • at FNAL

  3. Neutrino spectra T2K Super-K SciBar at BooNE K2K Near Physics motivation • Precise s measurement for T2K • CC-QE (using HARP results) • CC-coherent p • CC-1p • NC-p0 Similar neutrino energy as T2K • Anti-neutrino s measurement • CC-QE • CC-coherent p The first measurement below 1GeV • Measurement for MiniBooNE • Flux x s measurement • Beam ne contamination hatched: nm spectrum w/ oscillation (Dm2=2.7x10-3 eV2)

  4. Pm, qm (Neutrino run) 5x1019 POT 1 track CC-QE CC-1p CC-coh. p CC-multi p qm Pm ~13,500 events QE~67% 2 track QE Pm qm ~1,970 events QE~76% Pm 2 track non-QE qm ~2,360 events CC-1p~49%

  5. Pm, qm (Anti-neutrino run) 1020 POT 1 track qm CC-QE CC-1p CC-coh. p CC-multi p nm BG Pm ~11,300 events QE~58% 2 track QE Pm qm ~630 events nm BG~77% 2 track non-QE Pm qm ~1,410 events nm BG~54% CC-1p~18% CC-coh. p~18%

  6. Schedule (an idea when money is available) ?

  7. Cost (Jananese budget request) Year2005 • SciBar disassemble ~2,000,000 (K2K Exp. budget?) • SciBar shipment ~5,000,000 (maybe ask to FNAL?) • WLS fiber ~5,000,000 • Replacement of the damaged one • Scintillator ~6,000,000 (New production at FNAL) • Replacement of the damaged one • Electronics repair and spare ~6,000,000 • PMT spare ~3,000,000 • Calibration system ~2,000,000 • Installation related. ~10,00,000 (No labor/technician fee include) • Glue, cables, etc.. (If we need PMT for ECAL ~40,000,000 => We must find the way) Total: ~30,000,000 + Travel Money: ~8000,000/year 3 students stay at FNAL (~4,000,000) 10 members visiting FNAL (~4,000,000) (*) Experimental Hall/Facility/Detector support structure/Cables/HV system/related cost are not included here since they will be covered by FNAL.
