Facility Support: The UCLA National Ion Microprobe

该奖项支持CAMECA /ims 1270 /高传输，高分辨率离子微探针在加州大学洛杉矶分校作为地质材料同位素微量分析的国家设施的继续运作。 研究工作将继续侧重于以高空间分辨率测定地质样品的年代，但目前正在地球化学和环境代用记录方面开展新的工作，除其他外，还将调查气候变化问题。 我们预计将接待50多名外部调查人员，代表大约一半的独立支持的NSF项目。 计划在未来三年的供资周期内进行硬件和软件的技术升级。 NSF基金为我们提供了稳定的支持来源，以开发新的分析协议，这将有助于我们更好地了解地球和我们在其中的位置，并使我们能够接待来自全国各地的科学家，他们将从我们世界一流的离子微探针实验室中受益。 除了对社区的直接利益之外，访问科学家和学生与UCLA工作人员之间的互动往往会催化和孵化反馈到我们学科的新想法。 作为世界上为数不多的类似设施之一，我们是地球化学和宇宙化学领域委托新离子探针实验室的训练有素的人员的主要来源之一。 在这方面，我们将举办一个年度研讨会，其中二十多名年轻科学家被带到加州大学洛杉矶分校进行为期一周的讲座和实验室演示，向下一代介绍离子微探针在地球科学中的潜力。

This award supports continued operation of the CAMECA /ims 1270 /high transmission, high resolution ion microprobe at UCLA as a national facility for isotopic microanalysis of geologic materials. Research will continue to focus on dating geological samples at high spatial resolution but new thrusts in biogeochemistry and environmental proxy records investigating, among other issues, climate change, are being pursued. We expect to host over 50 external investigators representing about half as many independently supported NSF projects. Technical upgrades, both hardware and software, are planned for the coming three year funding cycle. NSF funds provide us a stable source of support to develop the new analytical protocols that will help us better understand the Earth and our place in it and allow us to host scientists from across the nation who benefit from access to our world-class ion microprobe laboratory. In addition to this direct benefit to the community, interactions between visiting scientists and students with UCLA staff tend to catalyze and incubate new ideas that feedback into our discipline. As one of only a handful of similar facilities world-wide, we are one of the principal sources of trained personnel to commission new ion microprobe laboratories in the field of geo- and cosmochemistry. In this regard, we will host an annual Workshop in which two dozen or so young scientists are brought to UCLA for a week of lectures and laboratory demonstrations to introduce the next generation to the potential of the ion microprobe in the geosciences.
