Tracing Antineutrino Direction with PROSPECT

PROSPECT, the Precision Reactor Oscillation and SPECTrum Experiment, is a short-baseline reactor-based neutrino experiment, examining the spectrum of antineutrinos emitted by the High Flux Isotope Reactor. Antineutrinos are detected through Inverse Beta Decay, a nuclear reaction which occurs when an electron antineutrino scatters off of a proton to produce a positron and neutron. The lithium doped liquid scintillator and optically isolated segments allow for precise event localization. As the neutron retains the direction of the antineutrino on average, PROSPECT is in a unique position to reconstruct the direction of incoming reactor antineutrinos.Directionality results from an analysis of PROSPECT data are compared to Monte Carlo simulations. This talk will present a comparison of the measured average antineutrino direction to the known reactor position, and methods used to cross-check the results using background radioactivity.
