Purchase of a Noble Gas Mass Spectrometer

9629556这笔赠款提供270,000美元，作为购买犹他大学诺贝尔气体质谱仪的部分费用，该质谱仪配备了离子计数电子设备、相关的提取和清理线路。这一仪器将使这些国际和平研究所能够利用惰性气体同位素系统学作为工具，对各种主题进行内部研究。具体的研究项目将包括使用~3H/3He技术测定地下水的年代和追踪地下水流动路径，使用宇宙产生的放射性核素如~3He和~(21)Ne确定火山地区冰川退缩的时间，确定灾难性洪水的时间，确定断层复发的间隔，以及利用含水层中的惰性气体测量重建大陆古温度记录。***

9629556 Cerling This grant provides $270,000 as partial support of the costs of acquiring a Nobel gas mass spectrometer equipped with ion counting electronics, associated extraction and clean up lines at the University of Utah. This instrument would allow these PI's to conduct in-house research on a wide variety of topics using noble gas isotopic systematics as a tool. Specific research projects uould include using the 3H/3He technique for dating groundwater and tracing groundwater flow paths, dating of geomorphic surface exposures using cosmogenically produced radionuclides such as 3He, and 21Ne for establishing the timing of glacial retreat in volcanic terrains, timing of cataclysmic floods, determining fault recurrence intervals, and reconstructing continental paleotemperature records using noble gas measurements in aquifers. ***
