Outline of Final Research Achievements |
Understanding of the behavior of an electron beam in an injector section is indispensable to achieve high-brightness electron beam acceleration. A lot of electron accelerator element parameter contributes to the injector section, and the understanding of behavior of an electron beam is difficult without optimizing all parameters of the injector section. So multi-objective optimization of the electron accelerator parameters was studied in this program. As a result, the GUI tool which is a basic tool of electron accelerator parameter multi-objective optimization study was developed also showed that a three-dimensional model of acceleration cavity is useful in the injector section.

Academic Significance and Societal Importance of the Research Achievements |
本課題で開発を進める最適化ツールは、加速器の研究開発、ビームダイナミクス研究において必要不可欠な数値計算ツールであり、新型の加速器開発、複雑な挙動を示す電子ビーム挙動の解明へ貢献できる。また、既存の加速器であってもバンチ電荷を大きく増加するなどの電子ビーム性能の向上を図る場合には、各加速器要素パラメータの最適化が必須であり、そのうえで、各加速器要素の必要な性能などを決定できる。 さらに、最適化ツールの実際の加速器への適用を計画しており、これが加速器開発初期段階から適用可能になれば、加速器の自動運転を可能する等、加速器の普及へ向けた大きなブレークスルーが期待できる。
