Abstract
Jinping Neutrino Experiment (Jinping) is a unique observatory for low-energy neutrino physics, astrophysics and geophysics. Jinping is located in China JinPing underground Laboratory (CJPL), identified by the thickest overburden, lowest reactor neutrino background, etc. For solar neutrinos, Jinping has the capacity to measure the oscillation transition phase from vacuum to matter, to discover the CNO cycle neutrino, and to address the solar metallicity problem. Jinping will be able to precisely measure geo-neutrinos with signal-to-background ratio of 8.2:1.0 in the energy range of 1.8 MeV to 3.3 MeV. The ratio of U/Th can be determined to 10%. We also expect a promising sensitivity for neutrinos from a Milky Way supernova, the diffuse supernova neutrino background, and dark matter annihilation. The first, small phase of the laboratory (CJPL I) is already in operation, hosting dark matter experiments. The second, large phase (CJPL II) is already under construction, with ≈ 100,000 m3 being excavated.
