| Outline of Final Research Achievements |
Evaluate the effect of the accuracy of nuclear reaction data on On-Line PET, which is a method for extracting the irradiation field using positron-emitting nuclides generated during proton beam therapy, and the dose calculation of normal cells by secondary neutrons in particle beam therapy. We confirmed the importance of accuracy of nuclear reaction data. Furthermore, we advanced the development of a detector for nuclear reaction data measurement. From the initial plan, we improved the multi-channel readout method using multiple MPPCs with the aim of downsizing the entire detector including the power supply and readout circuit and generalizing the detector itself. The situation around the research subject has changed from the beginning of the research, and we plan to continue development as a versatile detector.

| Academic Significance and Societal Importance of the Research Achievements |
粒子線治療における原子核反応データの整備が十分でないことを指摘し、現状の原子核反応データの測定精度が、粒子線治療における二次中性子による正常細胞への被ばく量評価及び陽子線治療における放射性核種を利用した照射野抽出精度に少なからず影響を与えることを確認した。更に、不足する原子核反応データを測定するための検出器開発を進めた。
