Facility Support: The UCLA National Ion Microprobe

该奖项支持加州大学洛杉矶分校继续使用Cameca/IMS 1270/高透射率、高分辨率离子微探头，作为地质材料同位素微量分析的国家设施。研究将继续集中在高空间分辨率的地质样品测年上，但正在寻求生物地球化学和环境替代记录方面的新进展，这些记录除其他外，调查气候变化等问题。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。计划在未来三年筹资周期内进行硬件和软件的技术升级。NSF基金为我们开发新的分析方案提供了稳定的支持来源，这些方案将帮助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，他们受益于我们世界级的离子微探针实验室。除了对社区的直接好处外，来访的科学家和学生与加州大学洛杉矶分校工作人员之间的互动往往会催化和孵化新想法，并将其反馈到我们的学科中。作为世界上为数不多的几个类似设施之一，我们是受训人员的主要来源之一，以委托在地球和宇宙化学领域建立新的离子微探测器实验室。在这方面，我们将主办一个年度研讨会，届时将有20多名年轻科学家来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测器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.
