中子散射和衍射是现代科学检测技术的重要领域之一,中子谱仪是实现中子检测的核心装置。中子薄膜器件及其光学系统可以实现中子束传输、聚焦、准直、极化等状态的调制,是构成中子导管、准直器、弯管、极化器、翻转器等中子光学装置的核心器件,可以提升中子传输效率,简化中子光学仪器结构,是中子谱仪功能实现和性能提升的关键。同济大学精密光学工程技术研究所,面向我国各类中子源应用谱仪开发的需求,聚焦中子薄膜器件关键制作技术创新,解决了中子超镜和极化中子薄膜翻转元件的制作问题;以高端薄膜器件支撑了高性能中子光学系统的研制,成功研制出中子导管部件、基于超镜的多层嵌套式中子聚焦系统、高通量高空间分辨率的中子多通道KB聚焦系统,成功应用于国内大型和小型中子源的谱仪装置,支撑了我国小角散射、粉末衍射、自旋回波等中子谱仪的自主研发和升级改造。
Neutron scattering and diffraction spectrometers are powerful tools used in modern scientific measurements. Neutron film elements and optics have become the key parts of guiders, collimators, benders, polarizers, and flippers, because they can transport, focus, collimate, and polarize neutrons. Currently, owing to the increase in the number of neutron facilities in China, the demand for neutron film elements and optics has also been increasing. In this paper, the development and applications of supermirrors, flippers, guiders, and focusing optics are presented based on the supermirrors at the Institute of Precision Optical Engineering (IPOE) at Tongji University.
