Calibration strategy of the JUNO experiment

We present the calibration strategy for 20 kton liquid scintillator central detector of Jiangmen Underground Neutrino Observatory (JUNO). By utilizing a comprehensive multiple-source and multiple-positional program, in combination with novel dual calorimetry technique exploiting two independent photosensors readout systems, we demonstrate that JUNO can achieve better than 1% energy linearity 3% effective resolution, required by neutrino mass ordering determination.
