Calibration Strategy of the JUNO Experiment

Abstract

We present the calibration strategy for the 20 kton liquid scintillator central detector of the Jiangmen Underground Neutrino Observatory (JUNO). By utilizing acomprehensive multiple-source and multiple-positional calibration program, in combinationwith a novel dual calorimetry technique exploiting two independent photosensors and readout systems, we demonstrate that the JUNO central detector can achieve a better than1% energy linearity and a 3% effective energy resolution, required by the neutrino massordering determination
