Description

The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector under construction 650 m underground in China. JUNO will feature a rich physics portfolio with neutrinos from many sources including nuclear reactors, supernovae, cosmic-ray interactions in the atmosphere, the Sun, and the Earth. The primary neutrino target will consist of a 35.4 m diameter acrylic sphere filled with liquid scintillator surrounded by 17,612 20" photomultiplier tubes (PMTs) and 25,600 3" PMTs providing around 78% photocoverage. JUNO is expected to achieve a 3% energy resolution at 1 MeV, allowing to determine the neutrino mass ordering to 3$\sigma$ with ~6 years of data-taking and measure ${\sin }^2{\theta }_{12}$, $\mathrm{\Delta }{m}_{21}^2$, and $\mathrm{\Delta }{m}_{32}^2$ to better than sub-percent precision. After a brief review of the legacy from the Daya Bay, Double Chooz and RENO experiments, this talk will provide a broad overview of the status and prospects of JUNO.
