Measurement of the Uranium-235 Antineutrino Spectrum by PROSPECT

Not scheduled


Mr Benjamin Foust (Yale University)


The Precision Reactor Oscillation and SPECTrum experiment, or PROSPECT, detector is designed to accurately measure the $^{235}$U antineutrino energy spectrum. The detector is located at the High Flux Isotope Reactor (HFIR), an 85 MW highly-enriched uranium (HEU) reactor with short reactor-on periods, such that over 99% of the antineutrino flux comes from $^{235}$U.

This poster presents the latest spectral results from PROSPECT. We compare the resulting spectrum to model predictions, and test the contribution of $^{235}$U towards potential high energy excess as seen in previous spectral measurements performed at nuclear power reactors.
