Outline of Final Research Achievements

In order to evaluate the performance of plastic scintillators and wavelength shifting fibers, we first constructed an acquired light quantity measurement system. The measurement system of the acquired light quantity was devised so that the energy of the excited radiation source becomes constant, and it was archived. In order to understand the basic performance of the scintillators, the excitation and emission wavelengths and the emission decay time were measured using synchrotron radiation from UVSOR. This result has not been sufficiently verified so far, and can be said to be a useful measurement for future measurement.

Academic Significance and Societal Importance of the Research Achievements

これまで高エネルギー・原子核実験ではプラスチックシンチレータの物性的特性について十分検証されてきておらず、今回の測定結果から新しい検出器の製作において有用な視点が得られたと言える。また波長変換ファイバーの利用は大型化がすすみ制作費用も増えていく高エネルギー・原子核実験のいるビッグサイエンスの領域において製作費・の削減という研究資金の有効利用という面で社会的な貢献も期待できる。
