... Fall 2001 . ... With heavy water as its target medium the Sudbury Neutrino Observatory (SNO) is designed to study solar neutrinos by measuring both the total flux of 8B neutrinos through the neutral-current interaction as well as the electron-type neutrino flux via charged-current dissociation of deuterium. By comparing the electron neutrino flux to the total solar neutrino flux, SNO can make a unique study of the solar neutrino deficit and a model independent test for neutrino oscillations. ...
