The optical and radiochemical purification of the scintillating liquid, which will fill central detector JUNO experiment, plays a crucial role in achieving its scientific goals. Given gigantic mass dimensions an unprecedented target value about 3% @ 1 MeV energy resolution, has set severe requirements on parameters scintillator, such as attenuation length (Lat>20 m at 430 nm), transparency, light yield, content radioactive contaminants (238U,232Th<10-15 g/g). To accomplish these needs,...
Several neutrino detectors, KamLAND, Daya Bay, Double Chooz, RENO, and the forthcoming large-scale JUNO, rely on liquid scintillator to detect reactor antineutrino interactions. In this context, inverse beta decay represents golden channel for detection, providing a pair of correlated events, thus strong experimental signature distinguish signal from variety backgrounds. However, given low cross-section interactions, development powerful event selection algorithm becomes imperative achieve...
