Outline of Final Research Achievements

I succeeded that beam orbit and energy were reconstructed by magnetic field, RF cavity power&phase, and optics parameters measured by wire scanner about shot by shot beam within measured errors. At the same time, I developed some nondestructive measurement system: energy dispersion, beam loss position, energy jitter source. These systems gave steady results for advanced accelerator, SuperKEKB LINAC.

Academic Significance and Societal Importance of the Research Achievements

最先端の加速器では高い性能、安定性が必要とされるが、建設直後に設計性能を満足することは稀である。そのため、性能のボトルネックの早期発見が重要となる。本研究はその早期発見のためのシステム開発を行ったものであり、最先端の加速器の早期性能向上に対して重要な役割を果たせることを示した。早期性能向上により全ての加速器を利用した研究、そして利用のさらなる広がりにより、社会全体の技術力の発展につながる。
