Combined Analysis of all Three Phases of Solar Neutrino Data from the Sudbury Neutrino Observatory
SNO Collaboration, B. Aharmim, S. N. Ahmed +121
We report results from a combined analysis of solar neutrino data from all phases of the Sudbury Neutrino Observatory. By exploiting particle identification information obtained fr…
Measurement of the and Total B Solar Neutrino Fluxes with the Sudbury Neutrino Observatory Phase-III Data Set
B. Aharmim, S. N. Ahmed, J. F. Amsbaugh +147
This paper details the solar neutrino analysis of the 385.17-day Phase-III data set acquired by the Sudbury Neutrino Observatory (SNO). An array of He proportional counters was…
Four methods for determining the composition of trace radioactive surface contamination of low-radioactivity metal
H. M. O'Keeffe, T. H. Burritt, B. T. Cleveland +15
Four methods for determining the composition of low-level uranium- and thorium-chain surface contamination are presented. One method is the observation of Cherenkov light productio…
Independent Measurement of the Total Active 8B Solar Neutrino Flux Using an Array of 3He Proportional Counters at the Sudbury Neutrino Observatory
SNO Collaboration
The Sudbury Neutrino Observatory (SNO) used an array of 3He proportional counters to measure the rate of neutral-current interactions in heavy water and precisely determined the to…
High sensitivity measurement of 224Ra and 226Ra in water with an improved hydrous titanium oxide technique at the Sudbury Neutrino Observatory
B. Aharmim, B. T. Cleveland, X. Dai +15
The existing hydrous titanium oxide (HTiO) technique for the measurement of 224Ra and 226Ra in the water at the Sudbury Neutrino Observatory (SNO) has been changed to make it faste…
An array of low-background He proportional counters for the Sudbury Neutrino Observatory
J. F. Amsbaugh, J. M. Anaya, J. Banar +71
An array of Neutral-Current Detectors (NCDs) has been built in order to make a unique measurement of the total active flux of solar neutrinos in the Sudbury Neutrino Observatory (S…
Measurement of the and Total B Solar Neutrino Fluxes with the Sudbury Neutrino Observatory Phase I Data Set
SNO Collaboration
This article provides the complete description of results from the Phase I data set of the Sudbury Neutrino Observatory (SNO). The Phase I data set is based on a 0.65 kt-year expos…
Measurement of 222Rn dissolved in water at the Sudbury Neutrino Observatory
I. Blevis
The technique used at the Sudbury Neutrino Observatory (SNO) to measure the concentration of 222Rn in water is described. Water from the SNO detector is passed through a vacuum deg…
A radium assay technique using hydrous titanium oxide adsorbent for the Sudbury Neutrino Observatory
T. C. Andersen, SNO Collaboration
As photodisintegration of deuterons mimics the disintegration of deuterons by neutrinos, the accurate measurement of the radioactivity from thorium and uranium decay chains in the…
Measurement of radium concentration in water with Mn-coated beads at the Sudbury Neutrino Observatory
T. C. Andersen
We describe a method to measure the concentration of 224Ra and 226Ra in the heavy water target used to detect solar neutrinos at the Sudbury Neutrino Observatory and in the surroun…
Measurement of Day and Night Neutrino Energy Spectra at SNO and Constraints on Neutrino Mixing Parameters
SNO Collaboration
The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates. For charged current events, assuming an undistorted B spectrum, the n…
Direct Evidence for Neutrino Flavor Transformation from Neutral-Current Interactions in the Sudbury Neutrino Observatory
SNO Collaboration
Observations of neutral current neutrino interactions on deuterium in the Sudbury Neutrino Observatory are reported. Using the neutral current, elastic scattering, and charged curr…
The Sudbury Neutrino Observatory
The SNO Collaboration
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…
