Facility Support: The Purdue Rare Isotope Measurement Laboratory

EAR-0242797Caffee 普渡大学稀有同位素测量实验室 (PRIME Lab) 可测量各种样品基质（包括岩石、土壤、水和空气）中的 10Be (t1/2=1.5 Myr)、26Al (0.705 Myr)、36Cl (0.301 Myr) 和 129I (16 Myr)。该提案的目标是完成升级计划，大幅增强 PRIME 实验室的功能。作为 NSF 机构，我们的目标是 1) 为 NSF 资助的地球科学研究人员测量 10Be、26Al、36Cl 和 129I； 2) 为那些缺乏设施的研究者自行进行分离化学操作； 3) 提高所有测量的精度，增加设施的吞吐量，并开发能够测量不常规测量的放射性核素的技术； 4) 举办充满活力的内部研究项目，涉及将这些放射性核素应用于各种地球科学项目，包括开发新的地球科学应用； 5）通过对本科生和研究生（来自普渡大学和其他大学）进行这些放射性核素测量和应用的各个方面的培训来满足我们大学使命的教育要求。在提案的第一年，我们的重点将是完成硬件改进，但我们预计所有放射性核素都会成功生产运行。在该提案的第二年，我们预计分析样本数量的生产力将会提高。***

EAR-0242797CaffeeThe Purdue Rare Isotope Measurement Laboratory (PRIME Lab) measures 10Be (t1/2=1.5 Myr), 26Al (.705 Myr), 36Cl (.301 Myr), and 129I (16 Myr) in a variety of sample matrices, including rock, soil, water, and air. The goals of the proposal are to complete an upgrade program that will substantially enhance the capabilities of PRIME Lab. As an NSF facility our goals are 1) to measure 10Be, 26Al, 36Cl, and 129I for NSF-sponsored geoscience investigators; 2) to perform separation chemistries for those investigators lacking the facilities to do so themselves; 3) to improve the precision of all measurements, to increase the throughput of the facility, and to develop techniques allowing the measurement of radionuclides not routinely measured; 4) to host vibrant in-house research programs involving the application of these radionuclides to a variety of geoscience programs, including the development of new geoscience applications; and 5) to meet the educational requirements of our university mission by training both undergraduates and graduate students (from Purdue University and other universities) in all aspects of the measurement and application of these radionuclides. During the first year of the proposal our emphasis will be on completing the hardware improvements however we anticipate successful productive runs on all radionuclides. During the second year of the proposal we anticipate increased productivity in terms of the number of samples analyzed.***
