Description
Eos is a four-ton detector developed to study hybrid neutrino detection with water-based liquid scintillator (WbLS), combining the directional sensitivity of Cherenkov light with the high photon yield of scintillation. A central objective is to demonstrate directional reconstruction of low-energy electrons in a medium where Cherenkov photons are embedded within a dominant scintillation signal. Tagged samples of collimated electrons are provided by a deployed directional beta source, enabling controlled studies of event topology. Using these data, we evaluate Cherenkov–scintillation separation and quantify the resulting directional reconstruction performance in Eos. This poster presents the reconstruction results obtained with the tagged beta source and discusses the current capabilities and limitations of directional reconstruction in the Eos detector.
