The SNO+ experiment: Overview and Status — •Arnd Sörensen, Valentina Lozza, Nuno Barros, Belina von Krosigk, Laura Neumann, Johannes Petzoldt, Axel Boeltzig, Felix Krüger, and Kai Zuber — IKTP, TU Dresden, D-01069 Dresden

The SNO+ (Sudbury Neutrino Observatory plus scintillator) experiment is the follow up of the SNO experiment, replacing the heavy water volume with about 780 tons of liquid scintillator (LAB). The unique location in the deepest underground laboratory in the world, and the use of ultra-clean materials makes the detector suitable for low energy neutrino studies.

The main objective of SNO+ is the search for neutrinoless double beta decay of 150Nd (5.6% natural abundance). For this phase the liquid scintillator will be initially loaded with 0.1% (optimal loading 0.3%) of natural Neodymium, allowing also searches for atmospheric neutrinos, 8B solar-neutrinos, geo-neutrinos originating from radioactivity in the earth, the possible observation of neutrinos from supernovae and the study of reactor oscillation. In a later phase, for the detection of pep and CNO solar neutrinos, the Nd will be removed from the liquid scintillator. A review of the general SNO+ setup, the physics goals and the current status will be presented.
