MRI-R2: Acquisition of X-Ray Computed Tomography System for Imaging of Heterogeneous Materials

技术摘要：该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。微聚焦x射线计算机断层扫描是研究不透明材料内部结构的一种多学科、多用途的工具。它将被学院用来研究非均质材料，包括球形和非球形颗粒的包装，地球物理流动，弹性和卷曲，生物材料，运动和有机超导体。该仪器能够分辨小于10微米的三维特征和150mm尺寸的样品，允许前所未有的测量，从第一性原理计算非均质材料的强度、电导率和热传导、流体渗透率和电磁散射特性。除了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射线仪器将对本科生、研究生和博士后的培养产生重大影响。克拉克大学是一所文科大学，大约有2200名本科生和800名研究生，有着让本科生参与积极学习经验的强大传统。这个提议的仪器还将补充谢尔曼-费尔柴尔德基金会最近的一项教育资助，该资助将包括原子力显微镜和射电望远镜在内的跨空间成像的主要科学设备纳入克拉克大学基于探究的科学课程。x射线系统将补充该设备，使研究人员和学生能够前所未有地进入材料的内部结构。概要：本奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。微聚焦x射线计算机断层扫描系统是一种多功能的工业仪器，可用于研究物理学、材料科学和生物物理学融合的一系列科学问题。作为克拉克大学的测量和诊断工具，它将使一系列新的变革性研究成为可能，从第一性原理计算不透明非均匀材料的性质。除了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射线仪器将对本科生、研究生和博士后的培养产生重大影响。克拉克大学是一所文科大学，大约有2200名本科生和800名研究生，有着让本科生参与积极学习经验的强大传统。这个提议的仪器还将补充谢尔曼-费尔柴尔德基金会最近的一项教育资助，该资助将包括原子力显微镜和射电望远镜在内的跨空间成像的主要科学设备纳入克拉克大学基于探究的科学课程。x射线系统将补充该设备，使研究人员和学生能够前所未有地进入材料的内部结构。

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.
