Introducing Eos: a hybrid neutrino detection technology demonstrator

Hybrid detector technology has the potential to revolutionize next-generation neutrino experimentation. With a powerful design capable of utilizing both Cherenkov and scintillation signatures simultaneously for advanced particle detection, hybrid detection provides the exciting prospect to use large-scale neutrino detectors, such as THEIA, to answer unknown questions within the Standard Model. What is the neutrino mass hierarchy? Is CP-violated in the leptonic sector? Do Majorana Fermions exist? Eos is a 20-ton technology demonstrator currently under construction in Berkeley, which aims to characterize novel technology in an integrated fashion in order to evaluate the event reconstruction potential afforded by these advances. Eos will test novel scintillators, including water-based liquid scintillator (WbLS), fast photon detectors, and spectral sorting using dichroicons. In demonstrating the capability of hybrid detection, Eos will help push the frontiers for next generation neutrino physics.
