About SNO+
SNO+ is a neutrino detector re-using the vessel and underground space from the original SNO experiment. Rather than the heavy water used in SNO, SNO+ uses liquid scintillator which gives off light at the slightest interaction. This makes SNO+ far more sensitive to neutrino interactions than SNO. One of the goals of SNO+ is to be the first experiment to detect neutrinoless double beta decay.
