SNO+ is the successor of the SNO experiment, where the heavy water has been replaced by 780 tons of liquid scintillator (linear alkyl benzene, LAB). SNO+ is located in the SNOLAB underground facility, near Sudbury Ontario Canada, 2 km below the surface to mitigate backgrounds produced by cosmic rays, and in a clean lab environment (class 2000) to reduce external backgrounds. The SNO+ experiment will use the infraestrcuture inherited from SNO, including the 12 m diameter acrylic vessel surrounded by almost 10000 PMTs, with some diverse modifications such as a hold-down rope net system and upgrades to the data acquisition. The physics programme will be initially focused in the search for the neutrinoless double beta decay, by adding tellurium to the scintillator (0.3 % by weight, 160 kg Te-130). The experiment will reach a sensitivity of 9×1025 yrs. (90 % C.L.) after 5 years of data taking. The limit will be reached due to the intense purification programme for the scintillator and tellurium. The physics goals of the experiment also include low energy solar neutrinos, geo and reactor neutrinos, supernova neutrinos if one occurs, as well as nucleon decay and dark matter search through axions. In this talk, I will present the current status of the SNO+ experiment and discuss its physics programme focusing in the double beta decay phase.
