Abstract
SNO+ is a multi-purpose Neutrino Physics experiment, succeeding to the Sudbury Neutrino Observatory by replacing heavy water with liquid scintillator, which can also be loaded with large quantities of double-beta decaying isotope. The scientific goals of SNO+ are the search for neutrinoless double-beta decay, the study of solar neutrinos and of anti-neutrinos from nuclear reactors and the Earth's natural radioactivity, as well as supernovae neutrinos. The installation of the detector at SNOLAB is being completed and commissioning has already started with a dry run. The detector will soon be filled with water and, later, with scintillator. Here we highlight the main detector developments and address the several Physics analysis being prepared for the several planned SNO+ runs.
Highlights
A new rope system holding the spherical acrylic vessel that separates the active volume from the outside water shielding is already in place, and its capacity to accommodate a positive buoyancy, will be tested as the detector is filled with water
In order to allow for an effective monitoring of the detector characteristics with reduced access to the active volume, direct light sources are located in the outer volume and crossing the inner sphere
Summary and Outlook SNO+ is completing the installation of the new systems in order to start data-taking in 2014
Summary
A new rope system holding the spherical acrylic vessel that separates the active volume from the outside water shielding is already in place, and its capacity to accommodate a positive buoyancy, will be tested as the detector is filled with water. SNO+ is a multi-purpose Neutrino Physics experiment, succeeding to the Sudbury Neutrino Observatory by replacing heavy water with liquid scintillator, which can be loaded with large quantities of double-beta decaying isotope. The active medium changed from heavy water in SNO to a specially designed liquid scintillator in SNO+, allowing for measurements below 1 MeV.
