摘要

The Taishan Antineutrino Observatory (TAO) is a satellite experiment of the Jiangmen Underground Neutrino Observatory, located near the Taishan nuclear power plant (NPP). The TAO aims to measure the energy spectrum of reactor antineutrinos with unprecedented precision, which would benefit both reactor neutrino physics and the nuclear database. A detector geometry and event visualization system was developed for the TAO. The software was based on ROOT packages and embedded in the TAO offline software framework. This provided an intuitive tool for visualizing the detector geometry, tuning the reconstruction algorithm, understanding neutrino physics, and monitoring the operation of reactors at NPP. Further applications of the visualization system in the experimental operation of TAO and its future development are discussed.
