Abstract
Solar neutrinos from the decay of 8B 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 8B 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 8B neutrinos will be presented and shown to be in good agreement, with predictions of solar models.
