Status of the Jiangmen Underground Neutrino Observatory

The Jiangmen Underground Neutrino Observatory is a multipurpose neutrino experiment designed to determine neutrino mass hierarchy and precisely measure oscillation parameters by detecting reactor neutrinos from the Yangjiang and Taishan Nuclear Power Plants, observe supernova neutrinos, study the atmospheric, solar neutrinos and geo-neutrinos, and perform exotic searches, with a 20-thousand-ton liquid scintillator detector of unprecedented 3\% energy resolution (at 1 MeV) at 700-meter deep underground. In this proceeding, the subsystems of the experiment, including the cental detector, the online scintillator internal radioactivity investigation system, the PMT, the veto detector, the calibration system and the taishan antineutrino observatory, will be described. The construction is expected to be completed in 2021.Comment: 6 pages, 5figure

JUNO PhD thesis award

For his thesis : "Software and hardware developments for the next-generation liquid scintillator detectors JUNO and OSIRIS"The work performed during his PhD includes two major contributions to the JUNO experiment: the development and integration of a novel muon track reconstruction algorithm into the JUNO framework, and the development of the full Geant4 detector simulation for the OSIRIS pre-detector, the simulation and estimation of the external background, as well as the contribution to its calibration system.No prize money

Reduction of the 14C background in the JUNO experiment

The Jiangmen Underground Neutrino Observatory (JUNO) will be a 20 kt liquid scintillator neutrino detector. Its main goal is the determination of the neutrino mass hierarchy from a precise measurement of the energy spectrum of anti-electron-neutrinos 53 km away from the emitting nuclear reactor cores. To precisely measure the oscillation pattern of the reactor spectrum an unpredecent energy resolution for this kind of detector of 3% at 1 MeV is needed. Pile-up events with background from radioactive decays such as those from 14C can spoil the reconstruction of the neutrino energy. In this talk methods for discriminating pile-up events are presented. These methods are in addition to a simple clusterization algorithm, the utilization of spherical harmonics and a Likelihood-test of the photon hit time informations
