How It Works

Inside Sudbury Neutrino Observatory

Built in the Nineties, the Sudbury Neutrino Observatory (SNO) is currently being refurbished to refocus its sights on some of the latest questions in neutrino research. Baptised SNO+, the new detector will reuse much of its predecessor’s infrastructure to hunt for the products of neutrino interactions but using a slightly different technique. Instead of heavy water, SNO+’s tank will be filled with a scintillator: a liquid that gives off light when charged particles pass through it. This will enable SNO+ to spot lower-energy neutrinos than before, broadening the scope of the facility’s research.
