Facility Support: The Purdue Rare Isotope Measurement Laboratory

该奖项为普渡稀有同位素测量实验室(Prime Lab)的运营提供部分支持，该实验室是一个加速器质谱仪，利用FN(8兆伏特)串列加速器测量极少量的稀有宇宙成因放射性核素铍-10、碳-14、铝-26、硅-32、氯-36、钙-41和碘-129。加速器质谱学技术是唯一能够分析这些同位素的技术，Prime Lab是代表美国地球化学研究界运营的此类分析的国家资源。对天然样品中这些核素的准确测量能够确定年龄，还可以用作示踪剂，以重建固体地球、海洋、地面和地表水以及大气的体积迁移。需要这种分析的内部和外部用户项目包括固体地球科学、行星科学、大气科学、生态学、考古学以及针对全球变化研究的广泛应用的研究人员。

This award provides partial support for operating the Purdue Rare Isotope Measurement Laboratory (PRIME Lab), an accelerator mass spectrometry facility making use of an FN (8 megavolt) tandem accelerator to measure extremely small concentrations of rare cosmogenic radioactive nuclides of beryllium-10, carbon-14, aluminum-26, silicon-32, chlorine-36, calcium-41, and iodine-129. The accelerator mass spectrometry technique is uniquely capable of analyzing these isotopes, and PRIME Lab is operated as a national resource for such analyses on behalf of the U.S. geochemical research community. Accurate measurements of these nuclides in natural samples enable determination of ages and can also be used as tracers to reconstruct the migration of volumes of the solid earth, oceans, ground and surface waters, and the atmosphere. In- house and outside user projects needing such analyses include researchers in solid earth sciences, planetary sciences, atmospheric sciences, ecology, archeology, and a wide range of applications directed at global change research.
