The SNO+ Experiment: Overview and Status — Arnd Sörensen, •Valentina Lozza, Belina von Krosigk, Marc Reinhard, and Kai Zuber — IKTP, TU 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 location in one of the deepest underground laboratories in the world, and the use of ultra-clean materials makes the detector suitable for low energy neutrino measurements and rare event studies.

The main objective of SNO+ is the search for neutrinoless double beta decay of 130Te (34% natural abundance). For this phase the liquid scintillator will be initially loaded with 0.3% of natural Tellurium, allowing also searches for 8B solar-neutrinos, geo-neutrinos originating from radioactivity in the earth, the possible observation of neutrinos from supernovae and the study of reactor oscillation.

A phase with pure liquid scintillator is then planned, which will allow the detection of pep and CNO solar neutrinos. A review of the general SNO+ setup, the physics goals and the current status will be presented.
