Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a medium-baseline reactor neutrino experiment currently under construction in southern China. $20\,\mathrm{kton}$ LAB-based liquid scintillator target is contained inside the Central Detector, a $35.4\,\mathrm{m}$ diameter spherical acrylic vessel. The scintillator light emitted from the Central Detector will be read out by the surrounding $17612 \,\,20”$ and $25600\,\, 3”$ photo-multiplier tubes, which are submerged inside a $40\,\mathrm{m}$ diameter cylindrical water pool acting as an active shielding detector. The main goal of JUNO will be the determination of the neutrino mass ordering at a statistical significance of about $3\,\sigma$ within $6 \,\mathrm{years}$ of data-taking using electron anti-neutrinos produced in two nuclear power plants at a distance of $\sim52.5 \,\mathrm{km}$. To achieve this, JUNO aims for an unprecedented $3\,\%$ energy resolution at $1 \,\mathrm{MeV}$. This resolution together with the detector’s low energy threshold will enable a broad physics program including the observation of solar neutrinos, geo-neutrinos, neutrinos from a close by core-collapse supernova and the diffuse supernovae neutrino background as well as competitive sensitivity to proton decay. Additionally, JUNO will be able to determine the neutrino oscillation parameters $\sin^2(θ_{12}),\, \Delta m_{21}^2$ and $\Delta m_{31}^2$ at the sub-percent level. The talk will present the design of the experiment, its status and its physics prospects.
