Measurement of the Reactor Antineutrino Spectrum from ${}^{235}$U Fission using PROSPECT

Abstract

PROSPECT is a short-baseline reactor antineutrino experiment designed to search for short-baseline sterile neutrino oscillations and perform a precise measurement of ${}^{235}$U reactor antineutrino spectrum from the High Flux Isotope Reactor at Oak Ridge National Laboratory. This measurement probes our understanding of recent anomalous results observed in reactor antineutrinos. PROSPECT uses a $\sim$4-ton optically segmented, ${}^6$Li-loaded liquid scintillator detector with high light yield, world-leading energy resolution, and excellent pulse shape discrimination. The latest antineutrino spectrum measurement results from ${}^{235}$U fissions at HFIR are reported.
