“…However, the short recoil tracks and the direction of the incoming particle are not effectively recoverable via current liquid scintillator techniques. Possible solutions foresee the use of direction-sensitive gas-filled detectors (e.g., CF 4 ) fulfilling the detection requirements posed by 40 K geoneutrinos [206] or the employment of Cherenkov neutrino detectors [216]. Other innovative neutral current approaches exploit the coherent scattering on nucleon, whose cross section is several orders of magnitude higher than IBD and elastic scattering on electrons.…”

The review is conceived to provide a useful toolbox to understand present geoneutrino results with a view to shed light on Earth's energetics and composition. The status of the geoneutrino field is presented starting from the comprehension of their production, propagation, and detection, and going on with the experimental and technological features of the Borexino and KamLAND ongoing experiments. The current understanding of the energetical, geophysical and geochemical traits of our planet is examined in a critical analysis of the currently available models. By combining theoretical models and experimental results, the mantle geoneutrino signal extracted from the results of the two experiments demonstrates the effectiveness in investigating deep earth radioactivity through geoneutrinos from different sites. The obtained results are discussed and framed in the puzzle of the diverse classes of formulated Bulk Silicate Earth models, analyzing their implications on planetary heat budget and composition. As final remarks, we turn our gaze to the prospects in the field of geoneutrinos presenting the expectations of experiments envisaged for the next decade and the engaging technological challenges foreseen.

Solar, terrestrial, and supernova neutrino experiments are subject to muon-induced radioactive background. China Jinping Underground Laboratory (CJPL), with its unique advantage of the 2400 m rock coverage and the long distance from nuclear power plants, is ideal for MeV-scale neutrino experiments. Using a 1-ton prototype detector of the Jinping Neutrino Experiment (JNE), we detected 343 high-energy cosmic-ray muons and (7.86±3.97) muon-induced neutrons from an 820.28-day dataset at the first phase of CJPL (CJPL-I). Based on the muon-induced neutrons, we measured the corresponding muon-induced neutron yield in liquid scintillator to be (3.44±1.86stat.± 0.76syst.)×10 −4μ −1g−1cm2 at average muon energy of 340 GeV. We provided the first study for such neutron background at CJPL. A global fit including this measurement shows a power-law coefficient of (0.75±0.02) for the dependence of the neutron yield at liquid scintillator on muon energy.

“…With its unique advantage of 2400 m rock coverage [14] and ∼1000 km distance away from commercial nuclear power plants, CJPL became an ideal place for rare-event exper-iments, such as searching for dark matter [15,16] and studying neutrino physics. The proposed Jinping Neutrino experiment (JNE) [17] can therefore serve as a perfect observatory for MeV-scale solar-, geo- [18,19] and supernova [20] neutrino physics.…”

Solar-, geo-, and supernova neutrino experiments are subject to muon-induced radioactive background. China Jinping Underground Laboratory (CJPL), with its unique advantage of 2400 m rock coverage and distance from nuclear power plants, is ideal for MeV-scale neutrino experiments. Using a 1-ton prototype detector of the Jinping Neutrino Experiment (JNE), we detected 343 high-energy cosmic-ray muons and (6.24±3.66) muon-induced neutrons from an 820.28-day dataset at the first phase of CJPL (CJPL-I). Based on the muon induced neutrons, we measured the corresponding neutron yield in liquid scintillator to be (3.13±1.84stat. ±0.70syst.)×10 −4 µ −1 g −1 cm 2 at an average muon energy of 340 GeV. This study provides the first measurement for this kind of neutron background at CJPL. A global fit including this measurement shows a power-law coefficient of (0.75±0.02) for the dependence of the neutron yield at liquid scintillator on muon energy.
