SNO and SNO+

The Sudbury Neutrino Observatory completed taking data in its third phase on November 28, 2006. In this phase {sup 3}He proportional counters deployed in the heavy water served as the detectors for the neutrons produced by neutral-current interactions from {sup 8}B solar neutrinos. With this ability to distinguish neutral current events the goal is to bring the total uncertainty for the neutral current signal below 5%. Several improvements in the analysis have sharpened the energy resolution. Improvements in SNO water systems have also lowered background levels during the third phase. These improvements allow for a lower analysis threshold and SNO is working on this also. After the heavy water is removed from the SNO detector, the plan is to fill the detector with a liquid scintillator. SNO+, as this is called, will be able to detect lower energy neutrinos such as the pep solar neutrinos, geoneutrinos and reactor antineutrinos. By loading the SNO+ scintillator with neodymium, a competitive neutrinoless double beta decay search is also possible.
