Description

Jiangmen Underground Neutrino Observatory (JUNO), a next generation underground
reactor antineutrino experiment, is proposed to determine the
neutrino mass hierarchy and precisely measure neutrino oscillation parameters using a
massive liquid scintillator detector underground. The experimental
hall, spanning more than 50 meters, is under a granite mountain of over 700 m overburden.
The central antineutrino detector, built with 35.4-meter
diameter acrylic sphere, contains 20 kilotons of liquid scintillator and ~18,000 20 inch PMTs
(and ~25,000 3 inch PMTs). The antineutrino detector is placed
in a water pool shielding system which also functions as an active water Cherenkov veto
detector. On the top of water pool is a Top Tracker system which
further improves the muon track reconstruction. The talk will present the project construction status
