The SNO+ Experiment: Reactor & Solar $\nu$ Prospects

The SNO+ experiment is a large-scale, multipurpose neutrino experiment situated 2 km underground at SNOLAB in Canada. Successor to the Sudbury Neutrino Observatory, the SNO+ detector has inherited much of the original infrastructure including the 12-m diameter acrylic vessel which serves as the main detector body. Initially filled with ultrapure water, the SNO+ experiment has completed operations as a water Cherenkov detector, having set new limits on multiple invisible nucleon decay modes, performed measurements on $^8\mathrm{B}$ solar neutrinos, and made the first observation of reactor antineutrinos in pure water. The detector medium has now been replaced with liquid scintillator, and a new physics programme is being pursued including measurements of solar neutrinos and $\Delta\mathrm{m}^2_{12}$ from reactor antineutrinos. The liquid scintillator will be doped with >4 tonnes of $^{\mathrm{nat}}\mathrm{Te}$ to enable a search for neutrinoless double beta decay.
