Abstract

By surrounding a dark matter detector with a layer of boron-loaded liquid scintillator, a highly efficient neutron veto can be produced. In Monte Carlo studies, a one meter thick layer of scintillator has a veto efficiency greater than 99.5% for nuclear recoil events induced by radiogenic neutrons, and a veto efficiency of more than 95% for nuclear recoil events produced by cosmogenic neutrons. The use of boron-loaded scintillator both reduces the veto-induced dead time by decreasing the neutron capture time and allows high neutron detection efficiency to be achieved in a relatively compact geometry.
