Abstract

SNO+, a large liquid scintillator experiment, is the successor of the Sudbury Neutrino Observatory (SNO) experiment. The scintillator volume will be loaded with large quantities of ¹³⁰Te, an isotope that undergoes double beta decay, in order to search for neutrinoless double beta decay. In addition to this search, SNO+ has a broad physics program due to its sensitivity to solar and supernova neutrinos, as well as reactor and geo anti-neutrinos. SNO+ can also place competitive limits on certain modes of invisible nucleon decay during its first phase. The detector is currently undergoing commissioning in preparation for its first phase, in which the detector is filled with ultra pure water. This will be followed by a pure scintillator phase, and then a Tellurium-loaded scintillator phase to search for neutrinoless double beta decay. Here we present the work done to model detector aging, which was first observed during SNO. The aging was found to reduce the optical response of the detector. We also describe early results from electronics calibration of SNO+.

SNO+: Physics program and status update

Journal Article Sibley, L. ; Collaboration: SNO+ Collaboration - AIP Conference Proceedings

Joining the current generation of neutrinoless double beta decay experiments, SNO+ is a kilotonne-scale liquid scintillator neutrino detector housed 2 km underground in Vale Canada Ltd’s Creighton Mine near Sudbury, Ontario, Canada. Through re-purposing existing hardware in place for the now decommissioned Sudbury Neutrino Observatory (SNO), and employing a rigourous materials purification and selection program, SNO+ will investigate neutrinoless double beta decay of {sup 130}Te. Owing to its size, SNO+ expects a sensitivity to the effective Majorana neutrino mass near 100 meV with a 0.3% loading of natural Te and several years of data collection.

SNO and SNO+

Journal Article Chen, M C - AIP Conference Proceedings

The Sudbury Neutrino Observatory completed taking data in its third phase on November 28, 2006. In this phase {sup 3}He proportional counters deployed in the heavy water served as the detectors for the neutrons produced by neutral-current interactions from {sup 8}B solar neutrinos. With this ability to distinguish neutral current events the goal is to bring the total uncertainty for the neutral current signal below 5%. Several improvements in the analysis have sharpened the energy resolution. Improvements in SNO water systems have also lowered background levels during the third phase. These improvements allow for a lower analysis threshold and SNOmore »« less

Background reduction in the SNO+ experiment

Journal Article Segui, L. - AIP Conference Proceedings

SNO+ is a large multi-purpose liquid scintillator experiment, which first aim is to detect the neutrinoless double beta decay of {sup 130}Te. It is placed at SNOLAB, at 6000 m.w.e. and it is based on the SNO infrastructure. SNO+ will contain approximately 780 tonnes of liquid scintillator, loaded with {sup 130}Te inside an acrylic vessel (AV) with an external volume of ultra pure water to reduce the external backgrounds. Light produced in the scintillator by the interaction of particles will be detected with about 9,000 photomultiplier’s. For the neutrinoless double beta decay phase, due to its the extremely low rate expected,more »« less

Recent Developments in Neutrino Science: A Whole Lot About Almost Nothing

Conference Norman, E B

Results from Super-K, SNO, and KamLAND provide strong evidence that neutrinos undergo flavor-changing oscillations and therefore have non-zero mass. The {nu}-disappearance observations by KamLAND, assuming CPT conservation, point to matter enhanced (MSW) oscillations with large mixing angles as the solution to the solar neutrino problem--a result consistent with the MSW parameters recently defined by these experiments. This requires that the observed neutrino flavors (e, {mu}, and tau) are not mass eigenstates, but are linear combinations of the mass eigenstates of the neutrino. However, such oscillation experiments can only determine the differences in the masses of the neutrinos, not the absolutemore »« less
