Outline of Final Research Achievements

Our final goal is development of a high-performance 2D-neutron detector. The detector consists of a neutron detection and image sensor parts. The neutron detector part is directly printed on the image sensor with fine printing technologies. This study is technique to manufacture fine structures with printing techniques. We employ a liquid dispensing and screen print system to make the fine structures. We make some fine structures and confirm to work as a neutron detector with photo diode and developed readout system.

Academic Significance and Societal Importance of the Research Achievements

高位置分解、高時間分解能を持つ中性子検出器を実現するために微細加工が可能な半導体画像検出器を用いて高性能な中性子検出器を実現するための研究開発を行った。中性子を検出すると可視光を発行するシンチレータを中性子検出部として採用しているが、このシンチレータを半導体画像検出器上に印刷技術を用いて直接形成するための製造技術の研究開発を行った。
