Data acquisition for the Helium and Lead Observatory

Michael A. Schumaker, A. Boeltzig, T. H. Burritt, C. A. Duba et autres

The Helium and Lead Observatory (HALO) is a dedicated supernova detector constructed in the underground facilities at SNOLAB in Sudbury, Canada. It is designed to detect neutrinos from a supernova within the Milky Way galaxy using lead blocks and3He neutron detectors. Analysis …

SEARCHES FOR HIGH-FREQUENCY VARIATIONS IN THE8B SOLAR NEUTRINO FLUX AT THE SUDBURY NEUTRINO OBSERVATORY

B. Aharmim, S. N. Ahmed, A. E. Anthony, N. Barros et autres

We have performed three searches for high-frequency signals in the solar neutrino flux measured by the Sudbury Neutrino Observatory, motivated by the possibility that solar g -mode oscillations could affect the production or propagation of solar 8 B neutrinos. The first search …

HALO – the helium and lead observatory for supernova neutrinos

C. A. Duba, F. A. Duncan, J. Farine, Alec Habig et autres

The Helium and Lead Observatory (HALO) is a supernova neutrino detector under development for construction at SNOLAB. It is intended to fulfill a niche as a long term, low cost, high livetime, and low maintenance, dedicated supernova detector. It will be constructed …

Independent Measurement of the Total Active B8 Solar Neutrino Flux Using an Array of He3 Proportional Counters at the Sudbury Neutrino Observatory

B. Aharmim, S. N. Ahmed, J. F. Amsbaugh, A. E. Anthony et autres

The Sudbury Neutrino Observatory (SNO) used an array of $^{3}\mathrm{He}$ proportional counters to measure the rate of neutral-current interactions in heavy water and precisely determined the total active (${\ensuremath{\nu}}_{x}$) $^{8}\mathrm{B}$ solar neutrino flux. This technique is independent of previous methods employed by …

An array of low-background 3He proportional counters for the Sudbury Neutrino \nObservatory

J. F. Amsbaugh, Juan‐Manuel Anaya, J. Banar, Thomas J. Bowles et autres

An array of Neutral-Current Detectors (NCDs) has been built in order to make a unique measurement of the total active ux of solar neutrinos in the Sudbury Neutrino Observatory (SNO). Data in the third phase of the SNO experiment were collected between …

Determination of the νe and total B8 solar neutrino fluxes using the Sudbury Neutrino Observatory Phase I data set

B. Aharmim, Rushdy Ahmad, S. N. Ahmed, R. C. Allen et autres

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 kiloton-year exposure of ${}^{2}{\mathrm{H}}_{2}$O (in the following denoted as ${\mathrm{D}}_{2}$O) to the …

Electron energy spectra, fluxes, and day-night asymmetries of 8 B solar neutrinos from measurements with NaCl dissolved in the heavy-water detector at the Sudbury Neutrino Observatory

B. Aharmim, S. N. Ahmed, A. E. Anthony, ALAIN BELLERIVE et autres

Results are reported from the complete salt phase of the Sudbury Neutrino Observatory experiment in which NaCl was dissolved in the $^{2}\mathrm{H}$${}_{2}\text{O}$ (``${\text{D}}_{2}\text{O}$'') target. The addition of salt enhanced the signal from neutron capture as compared to the pure ${\text{D}}_{2}\text{O}$ detector. By …

Search for periodicities in the B8 solar neutrino flux measured by the Sudbury Neutrino Observatory

B. Aharmim, S. N. Ahmed, A. E. Anthony, Eugene W. Beier et autres

A search has been made for sinusoidal periodic variations in the $^{8}\mathrm{B}$ solar neutrino flux using data collected by the Sudbury Neutrino Observatory over a 4-year time interval. The variation at a period of 1 yr is consistent with modulation of the …
