SHRIMP SI - Microscale stable-isotope analysis in the Earth Sciences

氧、碳和硫等元素的稳定同位素变化，保存了地球和行星地质、生物和气候演化过程中最深刻的环境条件记录。我们将建造一个稳定同位素离子微探针（SHRIMP SI），以前所未有的细节检查地外和地球系统。在陆地应用中，主要问题是20微米点的精度达到0.01%，我们可以将其应用于地球上生命的发展、气候记录、风化和矿体形成的研究。太阳风和彗星的样本返回任务将提供与我们太阳系形成有关的独特样本。

Stable-isotope variations of elements such as oxygen, carbon, and sulphur, preserve the most profound records of environmental conditions during the geological, biological, and climatic evolution of Earth and planets. We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent level for 20-micron spots, which we can apply to studies of development of life on Earth, climatic records, weathering, and formation of ore bodies. Sample return missions of solar wind and comets will provide unique samples related to the formation of our solar system.
