Description
The Jiangmen Underground Neutrino Observatory (JUNO) is an experiment being built in China, which consists of a 20 kt liquid scintillator detector. The main objective of the experiment is to determine the neutrino mass ordering by measuring reactor anti-neutrinos at 53 km baseline. The experiment is also expected to have a high sensitivity to geoneutrinos, electron antineutrinos from natural radioactivity decay chains of 238-Uranium and 232-Thorium in the Earth. The radiogenic heat released in these decays is in a well established relationship with the abundances of Uranium and Thorium. Thus, the measurement of geoneutrino flux can provide an insight on the Earth's energy budget. Even more, distinguishing the signal coming from the Earth's mantle is a key feature which can unveil its convection scheme and contribution to the total radiogenic heat. Within the first year of data taking, JUNO will be able to exceed the total statistics of both Borexino and KamLAND experiments. With increased statistics, JUNO will be able to measure Uranium and Thorium fluxes individually and to establish their ratio, yet another important parameter for the geo-science community, giving insights about the Earth's formation process.
The talk will focus on the geoneutrino's sensitivity study at the JUNO experiment, reporting the expected precision of measuring the total and independent contributions of geoneutrinos from U and Th.
