Key Details

RED-100 is a two-phase liquid xenon detector situated very near a 3 GW reactor core

The goal is detecting coherent neutrino scattering for low energy antineutrinos

Ambient gamma rays and neutrons were characterized and are at acceptable levels

Cosmic muons are the main background, but can be identified and removed

Detecting reactor antineutrinos with liquid xenon

This paper describes the RED-100 experiment, which uses a two-phase liquid xenon detector to detect low-energy antineutrinos from a nuclear reactor core. The goal is to observe coherent elastic neutrino-nucleus scattering for the first time. The experiment is located very close to the reactor core to maximize neutrino flux. Researchers characterized background radiation at the experiment site, showing gamma rays and neutrons are at acceptable levels. The main background is from cosmic ray muons interacting in the detector, but this background can be identified and removed. Overall the detector and site enable a sensitive search for the elusive neutrino scattering process.
