Outline of Final Research Achievements

This project aims to further improve new photon detector using hybrid technology, which was developed in the research program previously approved. Here, an improvement includes photon imaging capability by adopting multiple anodes as a signal extraction and check new photocathode material to increase quantum efficiency. In addition, this research program examines possible usage of this photon detector inside the magnetic field by introducing the shield cage. It is also important for this study is to show new directions for the photon detectors. The 4 prototype detectors organized the photon detection system with readout electronics, where silica aerogel layer was used as a Cherenkov radiator. In this setup, the performance was tested with cosmic rays and detailed studies have been done, The magnetic shield cage was studied with improved computer simulation software.

Academic Significance and Societal Importance of the Research Achievements

近年において光検出器の開発は、素粒子物理学だけでなく宇宙からのシャワーの研究やPETなど医療関係において重要となってきている。その中で、安全な電圧で使用できることは専門でなくても使用できる可能性を広げるものである。また、より微弱な信号をとらえることは、今までにない精度のよい測定に貢献できるものである。それらに加え、光検出の位置情報を得ることは、光量に加え新しい測定を得ることで、正確な解析を進めること可能となる。本研究はこのような点を追求し、新しい光検出器の開発をさらに進展させるものである。
