Reactor Antineutrino Directionality Measurement with the PROSPECT-I Detector

The Precision Reactor Oscillation and SPECTrum (PROSPECT) experiment is a short-baseline reactor experiment intended to measure the antineutrino spectrum and search for the existence of sterile neutrino oscillations. Electron antineutrinos, emitted from the High Flux Isotope Reactor at Oak Ridge National Laboratory, are detected through inverse beta decay interaction. The PROSPECT-I detector has demonstrated the highest signal-to-background ratio on any surface antineutrino detector and has several features that enable measurement of the direction of a compact neutrino source. This talk will present the measurement of reactor antineutrino direction and comparisons of the data and simulation results to the known reactor position.
