The JUNO experiment in China
The JUNO (Jiangmen Underground Neutrino Observatory) experiment is an international collaboration to which the Leprince-Ringuet Laboratory (LLR) of École Polytechnique participates. The goal is to measure the mass of particles called neutrinos. The kick-off meeting was on January 10, 2015.
The kick-off meeting took place on January 10, 2015. JUNO ("Jiangmen Underground Neutrino Observatory") is an international experiment taking place in China, to which the Leprince-Ringuet Laboratory (LLR) of École Polytechnique participates. The goal of this experiment is to determine the neutrino mass hierarchy, but also observe supernova neutrinos, study the atmospheric, solar neutrinos and geo-neutrinos.
The existence of neutrinos was postulated for the first time in 1930 to solve a problem related to energy conservation. The neutrinos are particles emitted by the Sun or by supernovae and their mass has not yet been determined by physicists. The measurements of the neutrino mass hierarchy could contribute to research related to determining the age and shape of the universe.
The JUNO detector, with a 20-thousand-ton liquid scintillator detector, will be built in a dedicated 700-meter deep underground site, near Canton in China. The experiments will start in 2020.
