中文摘要 | 軟X光與物質的交互作用可提供有關物質中電子與磁性結構的重要訊息。隨著同步輻射光源亮度的日益提升,非彈性軟X光散射儀已成為研究前瞻性材料低能量激發現象的實驗利器。本文介紹一座嶄新的非彈性軟X光散射儀,此儀器的設計概念起源於能量補償原理之應用以及主動式光柵的研發。實驗結果顯示,應用能量補償原理所設計的非彈性軟X光散射儀,其量測效率可達傳統設計的百倍,而為探測物質之微觀電子與磁性結構開啟令人振奮的新契機。 |
英文摘要 | The interaction between soft-X-rays and matter can provide valuable information on the electronic and magnetic structure of matter. Facilitated by the increasing brilliance of synchrotron radiation light sources, inelastic soft-X-ray scattering (ISXS) has become a powerful technique for studying the low energy electron excitations of advanced materials. In this article, we present the design of a novel ISXS instrumentation which design stems from the application of energy compensation principle and the development of active gratings. The experimental results demonstrate that the data acquisition efficiency of this energy-compensation type ISXS instrumentation can be 100 times higher than conventional designs, opening up new opportunities for probing the microscopic electronic and magnetic structure of matter. |
