Description
The next-generation experiment JUNO (Jiangmen Underground Neutrino Observatory), expected to begin operation in 2021, will advance the capability of reactor neutrino experiments to determine neutrino mass ordering and precisely measure several neutrino mixing parameters. JUNO also has rich physics programs on astroparticle physics such as supernova-neutrinos, solar-neutrinos and geo-neutrinos, as well as proton decays and other exotic searches. JUNO has one 20-kton liquid-scintillator (LS) antineutrino detector (the central detector), two redundant muon veto systems, complementary calibration systems, and FADC readout electronics system. The designed energy resolution of 3%/sqrt(E) is expected to be achievable with the high photocathode coverage and highly transparent liquids. There are enormous engineering and technical challenges in building a 20-kton LS detector with unprecedented energy resolution. Here the design of JUNO and new technical advances of JUNO instrumentation will be introduced, with particular focus on the progress of central detector, the production and testing of high-efficiency MCP-PMT, strategy for highly transparent and radio-pure liquid scintillator, comprehensive energy calibration program, progress of electronics and veto system, etc.
