摘要

SNO+ is the successor to the Sudbury Neutrino Observatory.  SNO+ will be filled with liquid scintillator in place of the heavy water that was in the original SNO experiment.  The neutrino physics goals of SNO+ include low energy solar neutrinos, reactor and geo antineutrinos, and supernova neutrinos.  In addition, 1.3 tonnes of Te-130 will be added to the liquid scintillator enabling SNO+ to search for neutrinoless double beta decay, with sensitivity to Majorana neutrino mass in the inverted mass hierarchy parameter region.  This talk will describe the SNO+ detector and will present the status of the experiment and preliminary results.
