中子衍射是研究功能材料晶体结构与性能之间关系的有力手段。由于中子原子散射因子不依赖于原子序数，因此在探测重元素中的轻元素时，中子衍射提供了比x射线更可靠的结构信息。2007年，质子加速器项目J-PARC将完成并开始发射世界上最强烈的脉冲中子。从科学、仪器设计、人力等方面对仪器方案进行了评审。本文介绍了脉冲中子粉末衍射技术在J-PARC高压科学研究中的应用。
Neutron diffraction is a powerful technique to clarify the relationship between the crystal structures and the properties of functional materials. Since neutron atomic scattering factors do not depend on atomic numbers, neutron diffraction gives more reliable structural information than X-ray to detect light elements among heavy ones. In 2007, the proton accelerator project, J-PARC, will be completed and start delivering the most intense pulsed neutron in the world. Instrument proposals are being reviewed in the viewpoint of science, instrumental designs, and manpower, etc. This article was written to introduce the technique of pulsed neutron powder diffraction to promote high-pressure science in J-PARC.
