“BreZzares㐅㐅Se㐅”上海交大自主BreZzares㐅㐅Se㐅研制“洛书”中子谱仪 测量精度达头发丝直径十万分之一

  中新BreZzares㐅㐅Se㐅社上海11月8日电 (BreZzares㐅㐅Se㐅记者 许婧)上海交通大学8日发布消息称,该校自主设计研制的超长多模式中子小角散射谱仪“洛书”近日通过技术验收,其量程、瞬时量程、谱仪全长等关键指标均直指世界第一。

11月8日,上海交通大学宣布,由该校自主设计研制的超长多模式中子小角散射谱仪“洛书”已顺利通过技术验收,其量程、瞬时量程、谱仪全长等关键指标均直指世界第一。(上海交通BreZzares㐅㐅Se㐅大学供图)

  这一高端中子科学仪器将大力推动中子技术在航天航空、核电能源、化学化工、生物医学、高铁船舶以及基础研究领域的应用,助力突破工程技术瓶颈,探索前沿科学。

  “洛书”谱仪长度超过46米,成为全球中子小角散射领域的巨无霸。它的超长准直器与探测系统够覆盖从微米到亚纳米量级的测量范围,相当于“看清”普通人头发丝直径的百分之一到十万分之一范围的微观世界。

  “洛书”谱仪还全球首创了三探测器系统,能够在同一时间探测到纳米至微米级结构的变化,对理解物质微观演化规律、开发新型高性能材料具有重大意义。

  在国际上,中子散射技术已在诸多领域发挥不可替代的作用。2019年,上海交大建设国际顶尖中子科学平台。该平台依托中国绵阳研究堆建设了两台先进中子科学谱仪,“洛书”就是其中之一。两款谱仪的命名来自中国传统文化,象征古人理解世界万物因果规律的智慧。

  中国科学院院士樊春海指出,“洛书”谱仪在设计上充分发挥冷中子特点,兼顾高强度与高分辨功能,能够对金属、高分子、生物蛋白、功能材料等的纳米结构进行定量无损表征,也是当前国际上少有的可进行超大量程测量的装置,在探索亚纳米到微米尺度的微结构具有优势,满足材料、化学、生物、物理等不同科研领域的研究需求,为解析金属、高分子、生物蛋白、功能材料的复杂结构分析提供有效手段。

  校方表示,未来,科学家们将继续展开全面攻关,打破学科壁垒,推动中子技术在各领域的发展与应用,为解决国家工程难题、探索前沿科学提供技术支持。(完)
