Abstract
The Jiangmen Underground Neutrino Observatory (JUNO) is a multiporpose neutrino experiment currently in construction in China. It is designed to determine the neutrino mass ordering, to precisely measure the oscillation param- eters, to perform solar neutrino spectroscopy and to study supernova neutrinos and geoneutrinos. JUNO’s Central Detector holds 20 kton of liquid scintillator (LS), as target mass. The LS is contained in a huge acrylic sphere of 35 m in diameter, which is equipped with more than 43000 photomultipliers tubes (PMTs). The acrylic sphere is supported by a stainless-steel structure. A Cherenkov water pool and a Top Tracker, as veto detectors, are added to the total structure. The liquid scintillator is the main core of JUNO, since it is the interacting target of the neutri- nos. Therefore, it is essential to know its optical properties in details. In particular, the scintillator refractive index and the group velocity play a crucial role in the photon propagation and need to be measured with high precision.
