SNO+ will be a new kilo-tonne scale liquid scintillator detector that will study neutrinos. The experiment will be located approximately 2km underground in VALE’s Creighton mine near Sudbury, Ontario, Canada. The heart of the SNO+ detector will be a 12m diameter acrylic sphere fill with approximately 800 tonnes of liquid scintillator which will float in a water bath. This volume will be monitored by about 10,000 photomultiplier tubes (PMTs), which are very sensitive light detectors.
