| Outline of Final Research Achievements |
We aim to achieve the discrimination of light output points to reduce backgrounds in a double-layer liquid scintillator detector, based on a light sensor sensitive to the wavelengths of the light source. Using a small prototype, we performed photon counting of the liquid scintillator with different wavelengths in scintillation using a combined system which consists of a wavelength shifting plate and a photomultiplier tube, and confirmed a discrimination ability as expected from a simulation. As a consequence, the study has reached the stage to start to discuss a detailed plan for a future large detector to discriminate light output points.
