Description

SNO+ is a multi-purpose neutrino detector located 2 km underground at SNOLAB, Canada. The experiment is in operation with 780 tonnes of liquid scintillator as its target mass. The high light yield, low background levels, and planned long-term operation make SNO+ suitable for precision measurements of high energy solar neutrinos (E > 5 MeV) and provide the opportunity to detect low energy solar neutrinos. Exploring the time profile of the scintillator light allows to access a wide range of information about the events in the detector, providing powerful tools to discriminate between backgrounds and solar neutrino signals. This poster will present the time-based event discrimination methods under development by the SNO+ collaboration, including event-by-event directionality that has recently been published. These methods are being optimized to maximize signal-to-background for solar neutrino (and for all) analyses.
