摘要：

Solar neutrinos from the decay of B-8 have been detected at the Sudbury Neutrino Observatory (SNO) via the charged-current (CC) reaction on deuterium and by the elastic scattering (ES) of electrons. The CC reaction is sensitive exclusively to electron neutrinos while the ES reaction also has a small sensitivity to muon and tau neutrinos. In addition, SNO has the capability to provide a measurement of the flux of all active neutrino flavours via the neutral-current (NC) reaction on deuterium. The flux of electron neutrinos from B-8 decays measured by the CC reaction and the flux of the ES reaction, assuming no flavour transformation, will be presented. These flux measurements provide evidence that there is a non-electron flavour active neutrino component in the solar flux. The total flux of active B-8 neutrinos will be presented and shown to be in good agreement with predictions of solar models.
