Query: PROSPECT-II Physics Opportunities   The Precision Reactor Oscillation and Spectrum Experiment, PROSPECT, has made
world-leading measurements of reactor antineutrinos at short baselines. In its
first phase, conducted at the High Flux Isotope Reactor (HFIR) at Oak Ridge
National Laboratory, PROSPECT produced some of the strongest limits on eV-scale
sterile neutrinos, made a precision measurement of the reactor antineutrino
spectrum from $^{235}$U, and demonstrated the observation of reactor
antineutrinos in an aboveground detector with good energy resolution and
well-controlled backgrounds. The PROSPECT collaboration is now preparing an
upgraded detector, PROSPECT-II, to probe yet unexplored parameter space for
sterile neutrinos and contribute to a full resolution of the Reactor
Antineutrino Anomaly, a longstanding puzzle in neutrino physics. By pressing
forward on the world's most precise measurement of the $^{235}$U antineutrino
spectrum and measuring the absolute flux of antineutrinos from $^{235}$U,
PROSPECT-II will sharpen a tool with potential value for basic neutrino
science, nuclear data validation, and nuclear security applications. Following
a two-year deployment at HFIR, an additional PROSPECT-II deployment at a low
enriched uranium reactor could make complementary measurements of the neutrino
yield from other fission isotopes. PROSPECT-II provides a unique opportunity to
continue the study of reactor antineutrinos at short baselines, taking
advantage of demonstrated elements of the original PROSPECT design and close
access to a highly enriched uranium reactor core.
