本项目隶属于国家重点基础研究发展计划。项目的主要任务包括:1)建设翠竹(Bamboo)热中子三轴谱仪(简称翠竹谱仪);2)利用中子散射对凝聚态物质中的磁相互作用进行研究。项目于2016年结题,期间按计划完成了翠竹谱仪的建设,并对铁基超导体中的自旋涨落进行了详细研究。依托项目发表SCI论文80余篇,包括Science、Nature Physics及Physical Review Letters等高档次杂志,取得了一系列重要的结果,达到了预期目标。1翠竹谱仪的建设与调试翠竹谱仪是由中国科学院物理 This project belongs to the national key basic research and development plan. The main tasks of the project include: 1) building a bamboo thermal neutron triaxial spectrometer (referred to as the bamboo bamboo spectrometer); and 2) studying the magnetic interaction in the condensed matter by neutron scattering. The project was completed in 2016, during which time the construction of the Bamboo Bamboo Spectrometer was completed and the spin fluctuation in the iron-based superconductor was studied in detail. Relying on the project published more than 80 SCI papers, including Science, Nature Physics and Physical Review Letters and other high-grade magazines, has made a series of important results, to achieve the desired goal. 1 Cui bamboo spectrometer construction and debugging Cui bamboo spectrometer by the Chinese Academy of Sciences
