摘要：
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector with primary physics goal of neutrino mass hierarchy determination and precise measurement of the 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 700 m deep underground laboratory. A multi-veto system will be built for cosmic muon detection and background reduction. The central detector will be submerged in the ultra pure water pool instrumented with about 2000 MCP-PMTs (20 inches) to serve as an active water Cherenkov detector for muon tagging. Both the pool walls and the central detector external surface will be coated with Tyvek reflector to increase the light collection efficiency. The muon detection efficiency will be > 95% for water Cherenkov detector. With this veto system, the cosmic muon induced fast neutron background can be reduced to the level of similar to 0.1 /day.
