Pulse Shape Discriminating $^6$Li-Doped Liquid Scintillator for the PROSPECT Experiment*

PROSPECT is a reactor antineutrino experiment consisting of a segmented $^6$Li-doped liquid scintillator antineutrino detector. The experiment, located at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, will begin physics data-taking in early 2018. To enable the reduction of copious cosmogenic backgrounds to the inverse beta decay antineutrino interaction signal, the PROSPECT collaboration has developed and produced a custom $^6$Li-doped liquid scintillator with powerful pulse-shape discrimination capabilities. In this talk, we will report the properties of the PROSPECT liquid scintillator and production of 5 tons of scintillator necessary for the operation of the PROSPECT experiment. We will also describe a novel $^2^2^7$Ac doping mechanism for in situ energy calibration and measurement of the relative efficiency of detector segments.
