MRI: Acquisition of a High Energy X-ray Tomography Scanner

这项主要研究仪器（MRI）奖的目标是获得一种多功能、强大、高能和高分辨率的x射线微断层扫描（micro-CT）系统，该系统有助于对各种材料的内部结构进行无损测绘，从而加强佛蒙特大学（UVM）的多学科研究和教育。自从大约40年前在医疗服务领域引入基于计算机的x射线断层成像以来，x射线计算机断层成像现在被应用于工程、地质学、材料科学、生物学和地能源等领域的各种自然、历史和工程材料的无损研究。这项最先进的技术提供了非破坏性、高分辨率的材料3D成像，使研究人员能够解决许多与基础设施安全、安全、健康和能源相关的当代、以前棘手的基础和应用研究问题，从而直接造福社会。该仪器将支持18名研究人员的研究和教育活动，他们来自土木、环境、机械、电气和生物工程、植物和土壤科学、地质学、历史保护、医学和材料科学等不同领域。随着这台仪器的初始用户和研究应用，相信这台微型ct的收购将为研究人员及其学生提供强大的新功能，从而带来新的校内外研究和培训合作。微型ct允许研究人员检查载荷、温度波动、流体注入以及流体如何被不同材料吸收的影响。它将使UVM研究人员能够进行与以下相关的变革基础和应用研究和教育：各种多孔介质（土壤，岩石，建筑材料）的运输，机械和热行为；地质物质表征；植物与土壤群落结构特征；材料研究范围从历史材料到智能材料以及生物和仿生材料。该仪器还将加强整个校园的课程设置。基于微型ct获得的结果的教育模块将被纳入诸如材料工程、土壤力学、地下水水文学、地球能源系统、通过多孔介质的流动和运输物理学、微观结构（地质学）、生物力学、运输过程、土壤科学和土壤水运动基础等课程中。

MRI: Acquisition of a High Energy X-ray Tomography Scanner for Multidisciplinary Research and Education The objective of this Major Research Instrumentation (MRI) award is to acquire a versatile, robust, high energy, and high resolution X-ray microtomography (micro-CT) system that facilitates nondestructive mapping of the internal structure of a variety of materials enhancing multidisciplinary research and education at the University of Vermont (UVM). Since the introduction of computer-based X-ray tomographic imaging in the medical services field about 40 years ago, X-ray computed tomography is now applied to the nondestructive study of various natural, historic and engineered materials in the fields of engineering, geology, materials science, biology, and geo-energy, among others. This state-of-the-art technology provides non-destructive, high resolution, 3D imaging of materials that enables researchers to tackle many contemporary, previously intractable, fundamental and applied research questions related to infrastructure security, safety, health, and energy, with direct benefits to the society. The instrument will support research and educational activities of eighteen investigators from diverse fields of civil, environmental, mechanical, electrical and bio engineering, plant and soil science, geology, historic preservation, medicine and materials science. With this initial set of users and research applications for the instrument, it is believed that the impact of the acquisition of this micro-CT will be substantial for providing powerful new capabilities for researchers and their students and will thus lead to new on- and off-campus research and training collaborations. The micro-CT allows researchers to examine the effects of loading, temperature fluctuations, fluid injections and how the fluids are absorbed by different materials. It will enable the UVM researchers to perform transformative basic and applied research and education related to: transport, mechanical and thermal behavior of a variety of porous media (soils, rocks, building materials); characterization of geological materials; characterization of plant and soil community structure; and materials research ranging from historic to smart materials and bio and bio-inspired materials. The instrument will also enhance curricular offerings across the campus. Educational modules based on the results obtained using the micro-CT will be incorporated into courses such as Materials Engineering, Soil Mechanics, Groundwater Hydrology, Geo-energy Systems, Physics of Flow and Transport through Porous Media, Microstructures (Geology), Biomechanics, Transport Processes, and Fundamental of Soil Sciences and Soil Water Movement, among others.
