0959066库德罗利·克拉克大学技术概述：该奖项是根据2009年美国复苏和再投资法案(公共法律111-5)资助的。微焦点X射线计算机断层扫描是一种研究不透明材料内部结构的多功能多学科工具。它将被教员用于研究非均质材料，包括球形和非球形粒子的堆积、地球物理流动、弹性和皱缩、生物材料、运动和有机超导体。该仪器能够在3D中分辨小于10微米的特征和大小达150 mm的样品，从而允许前所未有的测量从基本原理计算非均质材料的强度、导电性和导热性、流体渗透性和电磁散射特性。除了可以作为伍斯特和邻近地区的科学和工程界的研究和诊断工具外，X光仪还将对本科生、研究生和博士后的培训产生重大影响。该仪器将在克拉克大学操作，这是一所拥有约2200名本科生和800名研究生的文科大学，有着让本科生参与积极学习体验的强大传统。这项拟议的仪器还将补充谢尔曼-费尔柴尔德基金会最近提供的一项教育赠款，该赠款旨在将空间尺度成像方面的主要科学设备，包括原子力显微镜和射电望远镜，纳入克拉克大学以探究为基础的科学课程。X射线系统将补充这一设备，使研究人员和学生能够前所未有地接触到材料的内部结构。莱曼摘要：该奖项由2009年美国复苏和再投资法案(公共法律111-5)资助。微焦点X射线计算机断层扫描系统是一种多功能工业仪器，可用于研究物理学、材料科学和生物物理学的一系列科学问题。它将使克拉克大学的一系列新的变革性研究成为一种测量和诊断工具，从第一性原理计算不透明非均匀材料的性质。除了可以作为伍斯特和邻近地区的科学和工程界的研究和诊断工具外，X光仪还将对本科生、研究生和博士后的培训产生重大影响。该仪器将在克拉克大学操作，这是一所拥有约2200名本科生和800名研究生的文科大学，有着让本科生参与积极学习体验的强大传统。这项拟议的仪器还将补充谢尔曼-费尔柴尔德基金会最近提供的一项教育赠款，该赠款旨在将空间尺度成像方面的主要科学设备，包括原子力显微镜和射电望远镜，纳入克拉克大学以探究为基础的科学课程。X射线系统将补充这一设备，使研究人员和学生能够前所未有地了解材料的内部结构。

0959066KudrolliClark U.Technical Summary: This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Microfocus x-ray computed tomography is a versatile and multidisciplinary tool for studying the internal structure of opaque materials. It will be used by the faculty to investigate heterogeneous materials including packing of spherical and non-spherical particles, geophysical flows, elasticity and crumpling, biological materials, locomotion, and organic superconductors. The instrument is capable of resolving features to less than 10 microns in 3-D and samples up to 150 mm in size, to allow unprecedented measurements to calculate strength, electric and heat conduction, fluid permeability, and electromagnetic scattering properties of heterogeneous materials from first principles. The x-ray instrument will have a significant impact on undergraduate, graduate and post-doctoral student training, besides being available as a research and diagnostic tool for the scientific and engineering community in Worcester and neighboring areas. The instrument will be operated out of Clark which is a liberal arts university with approximately 2200 undergraduates and 800 graduate students, with a strong tradition of involving undergraduate students in active learning experiences. This proposed instrument will also complement a recent education grant by the Sherman-Fairchild foundation to bring major scientific equipment on imaging across spatial scales including an AFM and a radio telescope into an inquiry-based science curriculum at Clark University. The x-ray system will complement this equipment allowing researchers and students unprecedented access to the internal structure of materials.Layman Summary: This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).A microfocus x-ray computed tomography system is a versatile industrial instrument that can be used to investigate a range of scientific problems at the confluence of physics, materials sciences, and biological physics. It will enable a new series of transformative research both as a measurement and diagnostic tool at Clark University to calculate properties of opaque inhomogeneous materials from first principles.
