The water-based liquid scintillator (WbLS) is a new material currently under development. It is based on the idea of dissolving
the organic scintillator in water using special surfactants. This material strives to achieve the novel detection techniques by
combining theCerenkov rings and scintillation light, aswell as the total cost reduction compared to pure liquid scintillator (LS).The
independent light yieldmeasurement analysis for the light yield measurements using three different proton beamenergies (210MeV,
475MeV, and 2000MeV) for water, two different WbLS formulations (0.4% and 0.99%), and pure LS conducted at Brookhaven
National Laboratory, USA, is presented. The results show that a goal of ∼100 optical photons/MeV, indicated by the simulation to
be an optimal light yield for observing both the Cerenkov ring and the scintillation light from the proton decay in a large water
detector, has been achieved
