Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator neutrino detector under construction in China, aiming to determine the neutrino mass hierarchy, one among other open questions in neutrino physics. The measurement of the oscillation pattern of reactor electron anti-neutrinos reaching the detector is expected to lead to a 3-4 σ sensitivity on the mass hierarchy within 6 years of data taking. The detector is designed to achieve an energy resolution of 3% at 1 MeV. In addition, the effect of the dark rate of the 18,000 20-inch PMTs must be carefully considered. A study of the realistic dark-noise and other background hits in the PMTs and their effect on the detection of low-energy events will be presented.
