Measurement of the rate of ve + d → p + p + e- interactions produced by 8B solar neutrinos at the sudbury neutrino observatory
Physical Review Letters 87:7 (2001)
Abstract:
The 8B flux from elastic scattering (ES) and charged current (CC) of electrons was recorded at the Sudbury Neutrino Observatory (SNO) between November 2, 1999 and January 15, 2001. Data were partitioned into two sets then analyzed. As a result, the first direct indication of a nonelectron flavor component in the solar neutrino flux was established.Measurement of the Rate of nu_e + d -> p+p+e- Interactions Produced by B-8 Solar Neutrinos at the Sudbury Neutrino Observatory

First neutrino observations from the sudbury neutrino observatory

Abstract:
The first neutrino observations from the Sudbury Neutrino Observatory are presented from preliminary analyses. Based on energy, direction and location, the data in the region of interest appear to be dominated by 8B solar neutrinos, detected by the charged current reaction on deuterium and elastic scattering from electrons, with very little background. Measurements of radioactive backgrounds indicate that the measurement of all active neutrino types via the neutral current reaction on deuterium will be possible with small systematic uncertainties. Quantitative results for the fluxes observed with these reactions will be provided when further calibrations have been completed.Sudbury neutrino observatory

Abstract:
The Sudbury Neutrino Observatory is a second-generation water Cherenkov detector designed to determine whether the currently observed solar neutrino deficit is a result of neutrino oscillations. The detector is unique in its use of D2O as a detection medium, permitting it to make a solar model-independent test of the neutrino oscillation hypothesis by comparison of the charged- and neutral-current interaction rates. In this paper the physical properties, construction, and preliminary operation of the Sudbury Neutrino Observatory are described. Data and predicted operating parameters are provided whenever possible.TeV blazars: Status of observations
