Detection of astrophysical neutrinos by core-collapse Supernovae in the JUNO Observatory

The Jiangmen Underground Neutrino Observatory (JUNO) (see http://juno.ihep.cas.cn) is a multipurpose neutrino experiment designed to determine neutrino mass hierarchy and measure oscillation parameters by detecting reactor neutrinos from the Yangjiang and Taishan Nuclear Power Plants, observe SuperNova (SN) neutrinos, study the atmospheric, solar neutrinos and geo-neutrinos and perform exotic searches, with a 20-thousand-ton liquid scintillator detector of at 700-meter deep underground. A feasibility study of neutrino detection by core-collapse Supernovae, especially in reconstructing of multi-flavour SN neutrino energy spectra, is the main goal of this proposal of PH.D. thesis with the opportunity to analyse the first data measured by the Observatory.
