Current status of the SNO+ experiment — •Valentina Lozza, Belina von Krosigk, Felix Krüger, Philipp Schrock, and Kai Zuber — TU Dresden, IKTP, 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 1000 tons of liquid scintillator (LAB) in order to shift the sensitive threshold to the low energy range. It is located in one of the mines near Sudbury at a depth of 6000 m.w.e., presently the deepest underground laboratory in the world. The natural rock shielding which reduces the cosmic muon flux to about 3 muon per hour, and the use of ultra-clean materials makes the detector suitable for neutrinos studies. The main physical goals are the detection of pep and CNO solar neutrinos, geo-neutrinos originated from radioactivity in the earth, the possible observation of neutrinos from supernova, the study of reactor oscillation. Complementing this neutrino program, SNO+ will also search for neutrinoless double beta decay. In this phase the liquid scintillator will be loaded with 0.1% natural Neodymium allowing the study of 150Nd (5.6% abundance) neutrinoless double beta decay. A review of the general SNO+ setup, the physics goals and the current status will be presentend.
