An automated X-ray powder diffraction system that will enable investigators at the University of Missouri-Rolla (UMR) to pursue research in the areas of materials science and X-ray powder diffraction techniques will be purchased. The proposed equipment would allow for obtaining diffraction data from specimens under a wide range of environmental conditions and the reduction of these data with a variety of computational algorithms. The X-ray diffraction community would also benefit from UMR obtaining this equipment as investigators at UMR are involved in the development of line profile analysis algorithms, enhancement and support of a community-developed Rietveld structure refinement code, and the development of quantitative analysis techniques for multi- component mixtures that do not require the preparation of standards. The new system will also replace obsolete and worn out equipment. One of the principal investigators (James) is an experienced and highly regarded scientist who had made several important contributions with regard to the structure of amorphous magnetic materials. His colleague, (Howard) is well regarded also.

将购买一套自动 X 射线粉末衍射系统，使密苏里大学罗拉分校 (UMR) 的研究人员能够在材料科学和 X 射线粉末衍射技术领域进行研究。 所提出的设备将允许在各种环境条件下从样本获取衍射数据，并通过各种计算算法减少这些数据。 X 射线衍射社区也将从 UMR 获得该设备中受益，因为 UMR 的研究人员参与了线轮廓分析算法的开发、社区开发的 Rietveld 结构细化代码的增强和支持，以及不需要准备标准品的多组分混合物定量分析技术的开发。 新系统还将取代陈旧和破旧的设备。 主要研究人员之一（詹姆斯）是一位经验丰富且备受尊敬的科学家，他在非晶磁性材料的结构方面做出了多项重要贡献。 他的同事（霍华德）也很受人尊敬。
