The Eos detector: construction and performance
ORAL
Abstract
There is a long history of discoveries and measurements in neutrino physics made by Cherenkov and scintillation-based neutrino detectors. A hybrid detector capable of utilizing both the prompt directional Cherenkov light and the low-threshold scintillation light would greatly improve background rejection and provide world-leading sensitivity to a broad range of neutrino physics topics. Eos is a 20-ton detector with an approximately 4-ton fiducial volume target now running at UC Berkeley. The detector utilizes fast photomultiplier tubes, a novel water-based liquid scintillator (WbLS) target, and spectral sorting to study Cherenkov/scintillation separation and low-energy direction reconstruction. This talk will overview the experiment and show final results using data taken with a pure water target prior to the deployment of WbLS in Eos.
