| Outline of Final Research Achievements |
We developed 6Li-loaded water-based liquid scintillator to detect the secondary neutrons effectively in particle therapy such as proton therapy. The 6Li-loaded water-based liquid scintillator is composed of a surfactant, lithium compound, Pseudocumene as organic solvent, and Diphenyloxazole as luminescent agent. The surfactant is used in order to mix water and organic solvent. We shed light on that sodium dodecyl sulfate as surfactant and lithium bromide as lithium compound are suitable for the components of water-based liquid scintillator. Then, we measured the light output and transparency of our handmade Li-loaded water-based liquid scintillator. The light output and transparency are the basic properties of liquid scintillator.
