Abstract
A better discrimination among different Earth's global models can be reached combining the results from several sites: new measurements of geoneutrino fluxes are highly awaited from SNO+ and from experiments proposed to the scientific community, as JUNO (Jiangmen Underground Neutrino Observatory). In particular, JUNO would provide a substantial increase of the detection sensitivity and of the event rate thanks to its 20 kton target mass. In this framework, we estimate the expected reactor antineutrino signals all over the world, with a particular focus on SNOLab (Sudbury Neutrino Observatory Laboratory), where the SNO+ detector is going to take data, and on the site candidate for hosting the JUNO experiment. The ratio between the expected reactor antineutrino signal in the geoneutrino energy window (RG) and the expected geoneutrino signal (G) is calculated all over the world in order to produce a RG/G map. In particular, by using the 2012 IAEA database, the RG/G ratios for SNO+ and JUNO are 0.9 and 0.7, respectively.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
