The design and expanded physics reach of the PROSPECT-II detector upgrade
ORAL
Abstract
The Precision Reactor Oscillation and SPECTrum (PROSPECT) experiment consists of a segmented liquid scintillator antineutrino detector located around 7m from the highly-enriched High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory that aims to explore short-baseline antineutrino oscillations.
Its first phase of data collection, called PROSPECT-I, ran from 2018 to 2019 and resulted in several high-precision analyses, including multiple 235U antineutrino spectrum measurements and eV-scale sterile antineutrino oscillation searches.
Following completion of its first run, the collaboration has developed an upgraded detector design, called PROSPECT-II, with the goal of improving the experiment's statistics and sensitivity. PROSPECT-II will provide unique access to oscillation parameter space at high mass splittings and new insight into the causes of discrepancies between reactor antineutrino spectrum predictions and measurements. This presentation will describe the design of the PROSPECT-II detector and the physics program it enables.
