Outline of Final Research Achievements

High Speed Image Delay Tube (HSIDT), which could manage images with 10MHz in nuclear and particle physics experiments by using particle beams, has been developed. HSIDT has an image delay capability by controlling photo-electron drift in the tube. A prototype of HSIDT has been designed and made. Basic performances were tested.

Academic Significance and Societal Importance of the Research Achievements

大強度の粒子ビームを使用する原子核・素粒子反応を測定する実験において、標的とその近傍でおこる粒子の入射・生成・崩壊等の特徴的な軌跡を認識できるようになり、統計精度の向上、及び、測定限界の開拓などが可能となる。粒子ビームに関わる研究開発等にも応用の道は広がると期待される。
