Support for Applications of Accelerator Mass Spectrometry inthe Earth Sciences

该项目将支持加速器的开发 2004年质谱仪在地球科学中的应用 罗切斯特大学核结构实验室。 AMS技术灵敏度的提高 分析同位素氯-36，碘-129，钙-41和 锇-186/187将是该项目的一个主要重点。另一 该项目的产品将是综合，在合作 与国家标准局合作， 氯和碘的浓度标准。 加速器质谱已经发展成为一种 这是一项重要的技术，因为在许多情况下， 灵敏度足以测量稀有同位素， 用来确定地质事件的年代， 地球内部的物质转移。

This project will support the development of Accelerator Mass Spectrometry (AMS) applications in the earth sciences at the Nuclear Structure Laboratory of the University of Rochester. Improvements in the sensitivity of the AMS technique for analyzing the isotopes chlorine-36, iodine-129, calcium-41 and osmium-186/187 will be a major focus of the project. Another product of the project will be the synthesis, in collaboration with the National Bureau of Standards, of accurate isotope concentration standards for chlorine and iodine. Accelerator Mass Spectrometry has developed into an important technique because it is in many cases the only method sensitive enough for the measurement of rare isotopes that can be used to date the age of geological events and to trace the transfer of matter within the Earth.
