Outline of Final Research Achievements |
Based on the results of 3D electro-magnetic simulation and structural/thermal analysis, a parasitic-mode damped cavity having a TM020-mode resonance frequency around 1.5 GHz was successfully designed. This cavity can be applied for the diffraction limited light source with the beam energy of 3 GeV. In addition, a low-power cavity model dedicated for electro-magnetic measurements was also manufactured, and it was confirmed that the cavity performances expected from 3D electro-magnetic simulation could be reproduced.

Academic Significance and Societal Importance of the Research Achievements |
本成果により、運用性及びメンテナンス性に優れた常伝導方式の高調波空洞の実現可能性が大いに高まった。常伝導方式でも超伝導方式に迫る性能を有する高調波空洞の実現は放射光源加速器分野の高調波空洞に関する常識を覆すことになり学術的意義が大きい。さらに、研究を進め実際の放射光リングにて安定なバンチ伸張運転をデモンストレーションできれば、世界中の既存施設においても高調波空洞の導入が一気に進むと思われる。
