Description
LiquidO is a revolutionary detection technique, which uses opaque organic scintillator and that consequently departs from the classical paradigm of highly transparent liquid scintillator (LS) detectors that has prevailed for decades. In LiquidO, scintillation light is confined near its creation point by the scintillation light's short scattering length due to the opaque nature and collected by a dense grid of wavelength shifting fibers. The resulting topological information, normally lost in transparent LS detectors, allows for powerful event-by-event particle identification including MeV-scale positrons, electrons and gammas and enables strong background suppression. Another advantage over classical LS detectors is the possibility of loading to unprecedented levels, since the high transparency is no longer required. In this talk, we give an overview of the LiquidO idea. We also show the first results from the 'micro-LiquidO' prototype detector, which provided the proof of principle of the light confinement. We conclude with further R&D plans.
