SNO+: SNO with Liquid Scintillator

We are investigating the possibility of filling the Sudbury Neutrino Observatory with liquid scintillator (called SNO+) after the physics program with heavy water is completed at the end of 2006. Located in the deepest underground site for neutrino physics, SNO+ has unique capabilities, including detection of pep and CNO solar neutrinos. SNO+ could also detect geo-neutrinos - neutrinos from radioactivity in the Earth - and is favourably located for such a measurement since it is surrounded by the Canadian Shield, a simple geological configuration. The possibility also exists to deploy double beta decay isotopes in liquid scintillator and a competitive next-generation search could be performed. For relatively low cost, the science program from SNO could be extended, providing early and continuing science output for the new SNOLAB.
