Description

SNO+ will be a large-volume underground liquid scintillator neutrino experiment at the SNOLAB facility, in Sudbury, Ontario, Canada. The physics reach of SNO+ is broad and covers many areas of neutrino physics including neutrinoless double beta decay, geo-neutrinos, reactor and low-energy solar neutrinos. To achieve the goals of the experiment, it is imperative to understand the properties of the proposed linear alkyl benzene (LAB) scintillator. This poster will describe laboratory measurements designed to investigate: (1) the scintillation light timing profiles due to alpha and beta-particle excitation of LAB, and the alpha/beta discrimination capability based on these timing distributions, (2) the electron energy scale linearity, and (3) ionization quenching in SNO+ scintillator.
