Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kton liquid scintillator detector located ~650 m underground in southern China. Its primary physics goal is to determine the neutrino mass ordering (NMO) by precisely measuring the energy spectrum of reactor antineutrinos at a baseline of ~53 km. Following nearly a decade of construction, the JUNO detector began official operation on August 26, 2025. This poster presents the current energy reconstruction methods for point-like events in the JUNO central detector. Using calibration and natural radioactivity data, we demonstrate the achieved energy resolution and spatial uniformity, which are key performance metrics essential for JUNO’s sensitivity to the NMO.
