Single volume liq. scintillator detectors KamLAND Borexino SNO+ 300ton liq.sci. Running since 2007. 1000ton liq.sci. Running since 2002. 1000ton liq.sci. completing final design and beginning initial construction.
Liquid scinitillator detectors Expected number of events(for 10kpc SN) Events/1000 tons • Inverse beta( ν e +p→e + +n) : ~300 events Spectrum measurement with good energy resolution, e.g. for spectrum distortion of earth matter effect. • CC on 12 C(ν e + 12 C→e+ 12 N( 12 B)) : ~30 events Tagged by 12 N( 12 B) beta decay • Electron scattering (ν+e - → ν+e - ) : • NC γ from 12 C(ν+ 12 C→ν+ 12 C+γ): Total neutrino flux, 15.11MeV mono-energetic gamma • ν+p scattering( ν+p→ ν+p): Spectrum measurement of higher energy component. Independent from neutrino oscillation. ~20 events ~60 events ~300 events
