Description
The Jiangmen Underground Neutrino Observatory(JUNO) is a next-generation neutrino experiment located 700m underground in Southern China. The detector will use a 20 kton liquid scintillator equipped with 17612 20-inch PMTs and 25600 3-inch PMTs, with the photocathode coverage reaching ~78%. The detector is designed to reach a high energy resolution of 3% at 1 MeV for neutrino mass ordering(MO) determination. Outside the central detector, the pool is filled with ultrapure water equipped with 2400 MCP PMTs as a veto system for cosmic muon detection. There is a top tracker on top of the water pool to determine the muon track. JUNO will measure the neutrino MO (3∼4σ) and the three neutrino oscillation parameters to the sub-percent level. JUNO also has a rich physics potential for supernova neutrinos, geo-neutrinos, solar neutrinos, and searching for new physics beyond the Standard Model. The subsystem development and production programs are well underway. This talk will mainly focus on the status of the JUNO experiment.
