The Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation liquid-scintillator reactor neutrino experiment under construction in Southern China. It is a multi-purpose experiment with a wide range of applications in neutrino physics, ranging from a mass-ordering (MO) determination to solar, geo-, and atmospheric neutrinos, detecting of Supernova neutrinos, and precision measurement on oscillation parameters. The JUNO central detector (CD) designs to an energy resolution of 3% at 1 MeV. The detector system will install in an over 50-meter-wide experimental hall, which recently excavates under 700 m of granite overburden. The CD contains a 35.4-meter diameter acrylic vessel filled with 20-kt of LAB-based liquid scintillator, making it the largest liquid-scintillator detector in the world. The scintillation light will be read-out by 17612 20" PMTs and 25600 3" PMTs, reaching a high photocathode coverage higher than 75%. The CD surrounds a water pool filled with ultrapure water equipped with 2400 PMTs; on top of the CD, a tracker completes the JUNO veto system for cosmic muons detection.
JUNO construction will complete in 2022. This talk presents the detector design and status of the experiment.
