Solar neutrino flux results measured with the Neutral Current Detector array in the Sudbury Neutrino Observatory (SNO)

In 2004, the Sudbury Neutrino Observatory (SNO) added an array of $^{3}$He proportional counters to the 1000 tonnes of heavy water. The Neutral Current Detector (NCD) array detects the neutrons liberated in the neutral current reaction of neutrinos on deuterium. The NCD measurement of the total flux of active solar neutrinos above 2.22 MeV is decoupled from the PMT-based measurements of the electron solar neutrino flux resulting in a smaller correlation between these fluxes in this phase than in the previous SNO results. The operation of the NCD array will be discussed. The solar neutrino flux results from this 385-live-day phase and the latest global combined fits for the solar neutrino mixing angle and mass difference will be discussed.
