While laboratory based 3D x-ray imagers are becoming as much a part of the toolkit available in materials science labs as traditional electron microscopy, most systems are equiped only to examine small 'dead' artefacts. Synchrotron based X-ray imaging on the other hand offers much more flexible use of experimental space and instrumental configuration as well as offering higher resolution, but access is limited for most users to a few days per year; precluding many important experiments; particularly those with complex sample environments which take many days to set up, or for which the change in state takes place over days.This project is aimed at establishing an X-ray tomographic imaging facility that will open up a wide range of land mark experiments far beyond the interests of the proposers. We will put in place a framework by which users from within the physical sciences and beyond can access the facility no matter where they are located in the UK. Emphasis will be on experiments that cannot easily be done on bench-top systems, nor are best suited to synchrotron research facilities, or simply require experimentation prior to a visit to a synchrotron. It is not possible to second guess all the applications that will arise, especially those proposed from outside the Univesity of Manchester, but examples where there is a proven need and interest from within the University of Manchester include: + fibrous architectures (biomaterials & paper/textiles): to test models for the performance of non-wovens and to optimise scaffolds for cell growth + crack propagation - using phase contrast to reveal crack initiation and high resolution region of interest studies to monitor crack growth rates and crack morlphologies + in-situ powder processing: to extract information in 3D about powder movement and consolidation + metallurgy: to use phase contrast to measure phase microstructures in 3D + corrosion and protection: to exploit high resolution imaging to monitor the evolution of intergranular stress corrosion in 3D + soft solids processing: using phase contrast to delineate how small changes in processing can lead to big changes in morphology + polymer composites: exploiting phase contrast to highlight damage; and monitoring damage evolution + biomaterials: extracting structures that can be modelled and tested virtually to learn natures lessons + porous media: to characterise initial structures and to measure their reponse to fluids, deformation etc + geological materials: to provide input data for seismic modelling and performance prediction + paleontology: exploiting phase contrast to reveal fossil structures + dental materials: to optimise formulation/microstructure /property relationsAs a strategic investment from the University, the Facility will be on open access to users from across the Engineering and Physical Sciences Faculty at the University of Manchester as well as those outside, for which access arrangements and support will be in place.The beamline-based facility will have much in common with those being developed by the proposers at synchrotron facilties. This will mean that experiments can be switched between the two according to need. It also means that some software developed will be transferable from one to the other.

虽然基于实验室的 3D X 射线成像仪正像传统电子显微镜一样成为材料科学实验室可用工具包的一部分，但大多数系统仅用于检查小型“死”制品。另一方面，基于同步加速器的 X 射线成像可以更灵活地使用实验空间和仪器配置，并提供更高的分辨率，但大多数用户的访问时间仅限于每年的几天；排除许多重要的实验；特别是那些需要许多天才能建立的复杂样品环境，或者状态变化需要几天时间才能发生的样品。该项目旨在建立一个 X 射线断层扫描成像设施，该设施将开辟广泛的里程碑式实验，远远超出提议者的兴趣。我们将建立一个框架，使物理科学领域内外的用户无论身在英国哪个地方都可以访问该设施。重点将放在无法在台式系统上轻松完成的实验，也不是最适合同步加速器研究设施的实验，或者只是需要在访问同步加速器之前进行实验。不可能对所有将出现的应用进行二次猜测，尤其是曼彻斯特大学外部提出的应用，但曼彻斯特大学内部已证明有需求和兴趣的例子包括： + 纤维结构（生物材料和纸张/纺织品）：测试无纺布性能模型并优化细胞生长的支架 + 裂纹扩展 - 使用相差揭示裂纹萌生和高分辨率感兴趣区域研究 监测裂纹扩展速率和裂纹形态 + 原位粉末加工：提取有关粉末运动和固结的 3D 信息 + 冶金：使用相衬测量 3D 中的相微观结构 + 腐蚀和防护：利用高分辨率成像监测 3D 中晶间应力腐蚀的演变 + 软固体加工：使用相衬来描述加工过程中的微小变化如何导致材料的大变化 形态+聚合物复合材料：利用相差来突出损伤； and monitoring damage evolution + biomaterials: extracting structures that can be modelled and tested virtually to learn natures lessons + porous media: to characterise initial structures and to measure their reponse to fluids, deformation etc + geological materials: to provide input data for seismic modelling and performance prediction + paleontology: exploiting phase contrast to reveal fossil structures + dental materials: to optimise formulation/microstructure /property relationsAs a 在曼彻斯特大学的战略投资下，该设施将向曼彻斯特大学工程和物理科学学院以及外部的用户开放，并为其提供准入安排和支持。基于光束线的设施将与同步加速器设施的提案者开发的设施有很多共同之处。这意味着实验可以根据需要在两者之间切换。这也意味着开发的某些软件可以从一种软件转移到另一种软件。
