Description
The Taishan Antineutrino Observatory (TAO, or JUNO-TAO) is a satellite detector of the Jiangmen Underground Neutrino Observatory (JUNO), located adjacent to the Taishan Nuclear Power Plant in Guangdong, China. The detector system consists of a central detector (CD), a water Cherenkov veto detector, and a top veto tracker. Its primary physics goal is to provide a high-precision reference spectrum of reactor antineutrinos for JUNO. The CD contains 2.8 tonnes of liquid scintillator, surrounded by Silicon Photomultipliers (SiPMs) with a high photosensitive coverage of 83.3%. The detector is operated at -50°C to suppress the SiPM dark noise. TAO has commenced stable physics data-taking in February 2026.This poster will present the central detector performance,including light yield,energy resolution,energy non-linearity,the level of electronics noise, and the evolution of event rates. These performance results demonstrate that the TAO detector possesses the necessary capabilities to fulfill its core physics mission.
