Description
As a satellite detector of the Jiangmen Underground Neutrino Observatory (JUNO), Taishan Antineutrino Observatory (TAO/JUNO-TAO) is positioned ~ 44 meters from a reactor core of the Taishan Nuclear Power Plant. Its ton-scale liquid scintillator detector, instrumented with high-coverage Silicon Photomultipliers (SiPMs) operating at cryogenic temperatures, achieves an exceptional light yield and outstanding energy resolution for precision reactor antineutrino spectroscopy via inverse beta decay. A key challenge in achieving this goal is the characterization and mitigation of muon-induced backgrounds. Cosmic-ray muons and their secondary products (e.g., fast neutrons, long-lived isotopes like Li-9/He-8) can create signals mimicking the antineutrino interaction. Muon-related backgrounds constitute one of the primary background sources at the TAO, an integral component in the overall analysis chain. This poster presents an overview of muons and their associated backgrounds at TAO.
