  Neutrons are a particularly dangerous background for direct WIMP dark matter
searches; their nuclear recoils with the target nucleus are often
indistinguishable from nuclear recoils produced by WIMP-nuclear collisions. In
this study, we explore the concept of a liquid scintillator neutron veto
detector that would allow direct dark matter detectors to potentially reject
neutrons with greater than 99% efficiency. Here we outline the construction and
testing of a small prototype detector and the potential implications of this
technology for future dark matter detectors.
