Description
The Taishan Antineutrino Observatory (TAO, also known as JUNO-TAO) is a satellite experiment of the Jiangmen Underground Neutrino Observatory (JUNO). TAO contains about 2.8 ton gadolinium-doped liquid scintillator and is placed at about 30 m from a reactor core of the Taishan Nuclear Power Plant. One of the physics goals of TAO is to provide a high-precision reactor antineutrino spectrum for JUNO. To measure a high-precision reactor antineutrino spectrum, energy response should be calibrated well. In this poster, a calibration strategy to calibrate the non-linear and non-uniform energy response of TAO is presented. Several artificial radioactive sources can be deployed to calibrate the non-linear energy response, and the uncertainty of non-linear response can be further improved by using $^{12}\rm B$ decay signals produced by the cosmic muons. Additionally, radioactive sources can be deployed in center-axis and off-center regions to calibrate non-uniform energy responses.
