The JUNO experiment[1] is the successor to Daya Bay. It envisages the construction of the world’s largest scintillator detector, which it will use primarily to detect reactor neutrinos, with the goal of determining the neutrino mass hierarchy.The cosmogenic muons, i.e. the muons created by the interaction of cosmic rays in the atmosphere, provide a potentially dangerous background. They can interact with the 12C inside the detector creating, among other things, the isotopes 9Li and 8He; some of their decays can emit a neutron, mimicking the double coincidence used to identify the IBD reactor neutrino signal.
