Description
SNO+ is a large liquid scintillator based experiment located in the SNOLAB underground laboratory in Sudbury, Canada. The SNO+ experiment uses the 12 m diameter acrylic vessel as well as the PMT array of the SNO detector, with several upgrades necessary to fill with liquid scintillator.
The main physics goal of SNO+ is the search for the neutrinoless double-beta (0n2b) decay with 130Te. During the initial double-beta phase, the liquid scintillator will be loaded with 0.5% natural tellurium, corresponding to 1330 kg of 130Te. SNO+ sensitivity to the effective Majorana neutrino mass will begin to explore the parameter space in the inverted hierarchy region. Higher Te loading are being developed and a SNO+ Phase II would extend sensitivity to the entire inverted hierarchy region.
Designed as a general purpose neutrino experiment, the low background levels and the low thresholds will allow to additionally measure the reactor neutrino oscillations, geo-neutrinos in a geologically-interesting location, watch for supernova neutrinos, and measure the low energy solar neutrinos, like low energy 8B, pep and CNO.
This talk will focus on the current status of the SNO+ experiment, its sensitivity, and in particular the solar and supernova neutrino measurements.
