Abstract
The JUNO experiment is a large liquid scintillator neutrino detector designed to determine the neutrino mass ordering with a sensitivity of 3-4σ in 6 years. JUNO is a huge detector under construction in the southern part of China. The active mass of the JUNO detector will be 20kton of organic liquid scintillator, which converts the released energy, causes by a neutrino interaction, into visible light. The fluorescence light propagates for about 17.5m, for an event at the center of the detector, before it is converted in electric signal by 17612 20-inch PMTs and 25600 3-inch PMTs.. Given the high mass of the detector and the high resolution required to determine the neutrino mass ordering (3% at 1 MeV), having an accurate description of the liquid scintillator in the JUNO Monte Carlo is mandatory. For this reason, at the Università degli studi di Milano, we built two small scale experiments to measure the emission time profiles for different particles and the light propagation measuring both the refractive index and the group velocity in the liquid scintillator.
