中新网广州8月13日电 (记者 许青青)中国散裂中子源“多物理谱仪关键技术与应用”项目科技成果鉴定会12日在东莞举行。此次鉴定会汇聚了来自松山湖材料实验室、大湾区大学(筹)、中国科学院物理研究所、中国科学院金属研究所、中山大学、北京大学深圳研究生院、香港中文大学、澳门大学、南方科技大学等机构的专家。
多物理谱仪是散裂中子源科学中心、东莞理工学院和香港城市大学共同建设的国内首台中子全散射谱仪，是粤港科技合作、协同创新的典范。它也是在中国散裂中子源上建成的第一台合作谱仪，为“中国科学院-香港地区中子散射科学技术联合实验室”和“粤港澳中子散射科学技术联合实验室”提供了关键支撑。
中国科学院高能物理研究所研究员、多物理谱仪负责人殷雯介绍，多物理谱仪运行三年来，已完成300多项用户实验，研究领域涵盖电池与能源、化学与环境、合金材料、稀土与磁性材料等多个领域。它为材料科学、物理学、化学、环境等领域提供了不同有序度的结构研究平台，并在服务国家重大需求、产业需求与基础研究领域取得了一批重要成果。
殷雯表示，多物理谱仪关键技术指标，如样品处单位功率中子通量，处于国际同类型谱仪的领先水平，谱仪衍射分辨率和实空间分辨率达到国际同类型谱仪的最好水平。在多物理谱仪的研制过程中，团队还成功研制了国产位置灵敏型氦三管探测器，并实现了工程应用，性能达到了国际先进水平。此外，团队自主开发的用于中子衍射与对分布函数数据规约的国产软件，构建了全散射数据采集与分析技术全链条，实现了中子全散射数据规约软件的国产化。
多物理谱仪的成功不仅展示了粤港澳大湾区在科技协同创新方面的成就，也为我国在材料科学等领域的发展提供了强有力的技术支持。随着多物理谱仪的应用越来越广泛，它有望成为推动我国科技创新和产业升级的重要力量。

News Title: “Guangdong-Hong Kong-Macao Greater Bay Area Launches First Chinese Neutron Total Scattering Spectrometer”
Keywords: Neutron Source, Greater Bay Area, Collaborative Innovation

Aug 13 (Xinhua) — A symposium on the technical and application achievements of the “Multi-Physical Spectrometer Technology and Application” project of China’s Synchrotron Radiation Facility was held in Dongguan on August 12. The symposium brought together experts from institutions such as the Nan Shan Lake Material Laboratory, the University of the Greater Bay Area (under construction), the Institute of Physics of the Chinese Academy of Sciences, the Institute of Metal Research of the Chinese Academy of Sciences, Sun Yat-sen University, the Shenzhen Graduate School of Peking University, the Chinese University of Hong Kong, the University of Macau, and the Southern University of Science and Technology.
The multi-physical spectrometer is the first neutron total scattering spectrometer in China, jointly built by the Synchrotron Radiation Facility, Dongguan Polytechnic, and the City University of Hong Kong. It serves as a model of collaboration and innovation in science and technology between Guangdong, Hong Kong, and Macao. The spectrometer is also the first cooperative spectrometer built on the China Synchrotron Radiation Facility, providing crucial support for the “Sino-Hong Kong Neutron Scattering Science and Technology Joint Laboratory” and the “Greater Bay Area Neutron Scattering Science and Technology Joint Laboratory.”
Professor Yin Wen, a researcher at the Institute of High Energy Physics of the Chinese Academy of Sciences and the chief scientist of the multi-physical spectrometer, introduced that in the three years since its operation, the multi-physical spectrometer has completed over 300 user experiments, covering a wide range of fields including batteries and energy, chemistry and environment, alloy materials, rare earths and magnetic materials. It has provided a platform for studying different levels of order in materials science, physics, chemistry, and environmental science, and has achieved significant results in serving national key needs, industrial needs, and basic research.
Yin Wen noted that the key technical indicators of the multi-physical spectrometer, such as the neutron flux per unit power at the sample position, are at the leading level of similar types of spectrometers internationally. The diffraction resolution and real-space resolution of the spectrometer are at the best level among similar types of spectrometers internationally. During the development of the multi-physical spectrometer, the team also successfully developed a domestically produced helium-3 position-sensitive detector, which has been applied in engineering and has achieved an international advanced level in performance. Additionally, the team’s independently developed software for neutron diffraction and the distribution function data encoding, which is domestically produced, has built a full chain of technology for the collection and analysis of total scattering data, realizing the domestication of neutron total scattering data encoding software.
The success of the multi-physical spectrometer not only showcases the achievements of the Guangdong-Hong Kong-Macao Greater Bay Area in collaborative innovation, but also provides strong technical support for the development of China in materials science and other fields. As the multi-physical spectrometer is applied more widely, it is expected to become an important force in promoting China’s technological innovation and industrial upgrading.
