中国先进研究堆中子织构衍射仪的研制与调试

摘要

The neutron texture diffractometer is one of important and commonly used neutron instruments in the international neutron scattering laboratories . Under the demands of texture measurement with neutrons from domestic user community , the neutron texture diffractometer has been built at China Advanced Research Reactor (CARR) .Currently ,the preliminary adjustment and calibration with neutrons for this instrument has been finished .In this paper ,the measurement principle and advantages of neutron texture diffractometer were briefly introduced . The key components and detailed characteristics for neutron texture diffractometer at CARR and the corresponding results of calibration and performance test were also presented .%中子衍射技术作为研究多晶材料内部织构的标准技术之一，在众多领域具有广泛应用。中子织构衍射仪目前已成为中子散射实验室的常规谱仪。针对国内织构测量分析需求而建的中子织构衍射仪作为中国先进研究堆首批建设谱仪之一，现已完成设计、建造和初步调试工作。本文结合谱仪建造的实际工作，较系统地介绍了中子织构衍射仪的测量原理与优势，以及中国先进研究堆中子织构衍射仪的特点、基本组成、性能指标和调试情况。
