Abstract
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detectorwith primary physics goal of neutrino mass hierarchy determination and precise measurement ofthe neutrino oscillation parameters, as well as the measurement of solar neutrinos, geo-neutrinos,supernova neutrinos and the diffuse supernova neutrinos. The detector will be built in a 700m deep underground laboratory. A multi-veto system will be built for cosmic muon detectionand background reduction. The central detector will be submerged in the ultra pure water poolinstrumented with about 2000 MCP-PMTs (20 inches) to serve as an active water Cherenkovdetector for muon tagging. Both the pool walls and the central detector external surface willbe coated with Tyvek reflector to increase the light collection efficiency. The muon detectionefficiency will be > 95% for water Cherenkov detector. With this veto system, the cosmic muoninduced fast neutron background can be reduced to the level of ~0.1 /day
