Description
The Taishan Antineutrino Observatory (TAO) is a satellite experiment of JUNO, featuring a ton-scale liquid scintillator detector located about 44 m from a reactor core at the Taishan Nuclear Power Plant. TAO detects reactor antineutrinos via inverse beta decay (IBD). An array of silicon photomultipliers (SiPMs) with high photocathode coverage and photon detection efficiency provides a high light yield. The SiPM dark noise is suppressed by orders of magnitude by cooling the detector to −50 °C.
The primary goal of TAO is a precision measurement of the reactor antineutrino energy spectrum. TAO will provide a high-resolution reference spectrum for JUNO, reducing the impact of reactor-flux and spectral-model uncertainties on oscillation analyses, and will offer a valuable benchmark for nuclear databases.
This talk presents TAO’s first precision measurement of the reactor antineutrino spectrum and summarizes the current experimental status and recent progress of the TAO experiment.
