Outline of Final Research Achievements

We have developed new plastic scintillator cured at room temperature, and advanced study from the knowledge and equipment of the previous study (KAKEN young research B 26800148, Hiroaki Ono), toward the practical use of new plastic scintillator. Basic properties and long term stability of light yield and light attenuation length have been evaluated.
From the measurement, long term stability seems to be lower than commercially available scintillator and we add the stabilizer additive to improve the stability.
In the study, we have observed better long term stability using stabilizer even though still we are optimizing additives to improve the performance, but our new plastic scintillator has been improved advance for practical usage.
