Workshop on Applications of Neutron and X-Ray Tomography for Geomaterials

利用x射线和中子层析成像技术进行无损、高分辨率成像已成为地球科学和地球工程研究中极有价值的工具。路易斯安那州立大学和海军研究实验室海底科学分部将于2010年3月1日至3日在新奥尔良共同主办GeoX 2010：第三届地质材料x射线CT国际研讨会。GeoX 2010继两次非常成功的GeoX研讨会（2003年在日本和2006年在法国）之后。美国国家科学基金会要求资助美国研究生和初级教师参加为期一天的预备研讨会，然后出席GeoX 2010。预备研讨会旨在教育这些技术的潜在新用户：(1)x射线和中子层析成像的基础知识；(2)基本的图像处理和分析技术，特别强调地质材料；(3)各种联邦、大学和私营部门的x射线和中子断层扫描设施。本材料将为考虑使用断层扫描进行研究的研究者提供基本的概念和背景，并为与会者做好准备，使他们能够从GeoX 2010的演讲和讨论中充分受益。讲习班前的资料将主要通过讲习班网站传播，并辅以电子邮件。潜在的参与者将被要求提交支持请求，这些申请将由研讨会组委会审查，目的是增加研讨会参与者的范围。与会者将收到研讨会前后的调查问卷；组织者和演讲者希望更好地了解参与者的关注点，以及这些关注点是否在研讨会前的教程中得到了充分的解决。该研讨会将为来自美国机构的研究生和初级教师提供资金，使他们能够在他们的研究中使用计算机和中子断层扫描。他们还将会见来自美国、欧洲和日本的经验丰富的研究人员，这将促进未来可能的合作。

Non-destructive, high-resolution imaging using x-ray and neutron tomography has become an extremely valuable tool in geoscience and geoengineering research. Louisiana State University and the Naval Research Laboratory, Seafloor Sciences Branch, will be co-hosting GeoX 2010: 3rd International Workshop on X-ray CT for Geomaterials in New Orleans, LA, March 1-3, 2010. GeoX 2010 follows two highly successful GeoX workshops (2003 in Japan and 2006 in France). NSF funding is requested to support U.S. graduate students and junior faculty participation in a one-day pre-workshop and then attendance at GeoX 2010. The pre-workshop is designed to educate potential new users of these technologies on: (1) fundamentals of x-ray and neutron tomography; (2) basic image processing and analysis techniques, with particular emphasis on geomaterials; and (3) various federal, university, and private sector x-ray and neutron tomography facilities. This material will provide essential concepts and background for investigators that are considering using tomography for their research and will prepare attendees so that they can fully benefit from the GeoX 2010 presentations and discussions.Dissemination of pre-workshop information will be primarily through the workshop web site supplemented by e-mailings. Potential participants will be asked to submit requests for support, and these applications will be reviewed by the workshop organizing committee with the goal of increasing the range of participants at the workshop. Participants will be given pre- and post-workshop questionnaires; the organizers and speakers wish to better know the participants concerns and whether or not those concerns were adequately addressed by the pre-workshop tutorials. The workshop will provide funds to graduate students and junior faculty from US institutions to attend the workshop which will enable them to utilize computed and neutron tomography in their research. They will also meet experienced researchers from US, Europe, and Japan which will foster possible future collaboration.
