Jiangmen Underground Neutrino Observatory, JUNO, is an upcoming large liquid scintillator (LS) reactor neutrino experiment, which has a 20 kton LS central detector and around 18000 20-inch photomultiplier- tubes. The primary physics goal of JUNO is to determine the neutrino mass ordering (NMO) by measuring the fine oscillation patterns precisely, which requires an unprecedented energy resolution around . For precise energy spectrum reconstruction, it is crucial to deeply understand the detector response. As the reactor neutrinos are detected via the inverse beta decay channel , where is crucial for energy reconstruction. A data-driven model to calibrate the energy response of in the detector has been developed with the help of calibration sources. The model provides a promising method for particle-dependent energy response calibration in LS detectors, which could be generally helpful for spectral fit analysis.
Apart from reactor neutrinos, JUNO is a multi-purpose experiment which has prominent potentials on other subjects. One of the most interesting topics is the exploration of core-collapse supernovae (CCSNe) neutrinos with the advantages of large target mass and low detection threshold. The convincing time structures of the neutronization burst phase provides a model-independent way to discriminate NMO. The low detection threshold is crucial for neutral-current detection and improves the sensitivities, which is a key advantage of LS detectors.
