Description
The talk covers two experiments with reactor electron antineutrinos: the Daya Bay and the JUNO experiment, including JUNO's near detector TAO. Both experiments are located in China.
The Daya Bay experiment observes reactor antineutrino flux and spectrum from several nuclear power plants of total thermal power of 17.4 GW on baselines of ~0.5 km and ~1.5. It uses 8 identically designed scintillator detectors with total target mass of 160 tonnes. The Daya Bay provides the most precise measurement of the neutrino mixing angle θ₁₃ and precision measurement of the neutrino mass splitting Δm²₃₂. The experiment provides also the limits on the sterile neutrino parameters, precision measurement of the reactor antineutrino flux and spectrum and their evolution.
The JUNO experiment will observe reactor antineutrino flux and spectrum on average baseline of 52 km. The 20 kt scintillator detector will start operation in 2021. The experiment will be sensitive to the neutrino mass ordering on a level of 3–4 standard deviations and to neutrino oscillation parameters Δm²₂₁, m²₃₂ and θ₁₂ on a sub-percent level. Not limited by the neutrino oscillation program JUNO will observe solar, atmospheric, geo- neutrinos and will be sensitive to SuperNova neutrinos, diffuse SuperNova background neutrinos and proton decay.
