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.***

普渡大学稀有同位素测量实验室（PRIME Lab）测量了各种样品基质中的10 Be（t1/2=1.5 Myr），26 Al（.705 Myr），36 Cl（.301 Myr）和129 I（16 Myr），包括岩石，土壤，水和空气。该提案的目标是完成一个升级计划，这将大大提高PRIME实验室的能力。作为一个国家科学基金会的设施，我们的目标是1）测量10 Be，26 Al，36 Cl和129 I为国家科学基金会赞助的地球科学调查; 2）进行分离化学为那些缺乏这样做的设施，自己的调查; 3）提高所有测量的精度，增加设施的吞吐量，并开发技术，允许测量的放射性核素不定期测量; 4）主办充满活力的内部研究计划，涉及这些放射性核素的应用到各种地球科学计划，包括新的地球科学应用的发展;和5）通过培训本科生和研究生（来自普渡大学和其他大学）在这些放射性核素的测量和应用的各个方面，以满足我们的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将成功地进行生产性运行。在提案的第二年，我们预计在分析样品数量方面的生产力将有所提高。*
