Abstract
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton LS detectorat 700-m underground. An excellent energy resolution and a large fiducialvolume offer exciting opportunities for addressing many important topics inneutrino and astro-particle physics. With 6 years of data, the neutrino massordering can be determined at 3-4 sigma and three oscillation parameters can bemeasured to a precision of 0.6% or better by detecting reactor antineutrinos.With 10 years of data, DSNB could be observed at 3-sigma; a lower limit of theproton lifetime of 8.34e33 years (90% C.L.) can be set by searching forp->nu_bar K^+; detection of solar neutrinos would shed new light on the solarmetallicity problem and examine the vacuum-matter transition region. Acore-collapse supernova at 10 kpc would lead to ~5000 IBD and ~2000 (300)all-flavor neutrino-proton (electron) scattering events. Geo-neutrinos can bedetected with a rate of ~400 events/year. We also summarize the final design ofthe JUNO detector and the key R&D achievements. All 20-inch PMTs have beentested. The average photon detection efficiency is 28.9% for the 15,000 MCPPMTs and 28.1% for the 5,000 dynode PMTs, higher than the JUNO requirement of27%. Together with the >20 m attenuation length of LS, we expect a yield of1345 p.e. per MeV and an effective energy resolution of 3.02%/\sqrt{E (MeV)}$in simulations. The underwater electronics is designed to have a loss rate
