Abstract
Solar neutrinos are an irreducible background for the SNO+ double beta decay experiment. Neutrino interactions in the SNO+ detector produce directional Cherenkov light which, if separated from the dominant scintillation light, would allow for neutrino direction reconstruction and elimination of solar neutrino signals. Other liquid scintillator detectors can benefit from direction information and understanding the factors that enable Cherenkov discrimination would be valuable. A Monte Carlo simulation was developed to determine whether this scintillation/Cherenkov discrimination is in fact possible. The effects of various factors including photomultiplier tube concentration and size, as well as different timing properties on the ability to perform photon discrimination were examined. Should it prove possible to distin- guish between the signals this will allow for a major improvement in the sensitivity of the SNO+ experiment and possible applications in other liquid-scintillator based detectors.
