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

利用X射线和中子层析成像的无损、高分辨率成像已经成为地球科学和地球工程研究中非常有价值的工具。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日在洛杉矶新奥尔良共同主办Geox 2010：第三届岩土材料X射线CT国际研讨会。Geox 2010是在两个非常成功的Geox研讨会(2003年在日本和2006年在法国)之后举办的。美国国家科学基金会申请资助，以支持美国研究生和初级教师参加为期一天的预备研讨会，然后参加Geox 2010。预备讲习班旨在教育这些技术的潜在新用户：(1)X射线和中子断层成像的基本原理；(2)基本图像处理和分析技术，特别侧重于地质材料；以及(3)各种联邦、大学和私营部门的X射线和中子断层成像设施。这份材料将为正在考虑使用断层摄影术进行研究的研究人员提供基本的概念和背景，并将使与会者做好准备，以便他们能够充分受益于Geox 2010的演示和讨论。研讨会前信息的传播将主要通过研讨会网站进行，并辅之以电子邮件。将要求潜在参加者提交支助请求，讲习班组织委员会将审查这些申请，以期增加讲习班的参加者范围。将向学员发放讲习班前和讲习班后的调查问卷；组织者和发言者希望更好地了解与会者所关注的问题，以及讲习班前的教程是否充分解决了这些问题。研讨会将资助美国机构的研究生和初级教师参加研讨会，使他们能够在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.
