EAR-0516725ValleyThis award supports a full-time technician in the Wisconsin Secondary-Ion Mass-Spectrometer facility (WiscSIMS) to help maintain and run a new Cameca ims-1280 ion microprobe. WiscSIMS will be a multi-user center of excellence in stable isotope geochemistry. The proposal to purchase the ion microprobe included letters describing projects from 52 scientists; many in fields where the application of in situ stable isotope analysis is certain to yield exciting new results such as Petrology, Paleoclimatology, Mantle Geochemistry, and Meteoritics with others in areas where such analysis has not yet been fully exploited but holds great promise such as Sedimentology, Environmental Science, Nanotechnology, Biochemistry, and Medicine. Our facility will take advantage of new multicollector technology and other advances of the 1280 instrument to focus on the specialized needs of the stable isotope community: high precision, small sample size, and in situ analysis. The broader impacts of this proposal will include the training and instruction of undergraduate, graduate, and post-doctoral students. The unique new capabilities of this facility will facilitate fundamental research into a wide range of topics of societal concern, including climate change, environmental remediation and medicine.

该奖项支持威斯康星州二次离子质谱仪设施（WiscSIMS）的全职技术人员，以帮助维护和运行新的Cameca IMS-1280离子微探针。 WiscSIMS将成为稳定同位素地球化学的多用户卓越中心。 购买离子微探针的建议书包括来自52位科学家的描述项目的信件;许多领域中原位稳定同位素分析的应用肯定会产生令人兴奋的新结果，如岩石学，古气候学，地幔地球化学和陨石学，以及其他领域中这种分析尚未得到充分利用，但具有很大的前景，如沉积学，环境科学，纳米技术，生物化学和医学。 我们的设施将利用新的多收集器技术和1280仪器的其他进步，专注于稳定同位素社区的专业需求：高精度，小样本量和原位分析。 这一提议的更广泛影响将包括本科生、研究生和博士后学生的培训和指导。该设施独特的新功能将促进对社会关注的广泛主题的基础研究，包括气候变化，环境修复和医学。
