Acquisition of a Multicollector Thermal Ionization Mass Spectrometer

罗格斯大学地质科学系将利用国家科学基金会和罗格斯大学共同提供的资金购买一台新的多接收器质谱仪。这种仪器对于NSF目前支持的三个主要项目所需的同位素分析至关重要：中美洲火山作用（大陆动力学/MARGINS/俯冲工厂），新泽西钻探（大陆动力学和ODP）和生物复杂性（海洋科学）。新的放射性同位素分析设施将补充该部最近购置的稳定同位素和惰性气体质谱仪。它还将取代目前正在使用的老化的TIMS，这是一个VG部门的单一收集器，于1986年投入使用，在过去15年中一直发挥着作用。正在进行的中美洲火山活动和晚白垩世至全新世海平面和全球气候变化研究项目将因新仪器而大大加强，并将使分析的样本数量大大增加。中美洲的研究将增进我们对活动弧系统中火山活动的了解，并在今后可能提高我们预测火山爆发的能力。新泽西钻探计划和生物复杂性研究重点关注全球气候变化，因此对重要的科学，社会和政治问题产生直接影响。

EAR-0213139FeigensonThe Department of Geological Sciences at Rutgers University will purchase a new multicollector mass spectrometer with funds provided jointly by the National Science Foundation and Rutgers University. This instrumentation is crucial for isotopic analyses required in three major projects currently supported by NSF: Central American volcanism (Continental Dynamics/MARGINS/Subduction Factory), New Jersey drilling (Continental Dynamics and ODP), and Biocomplexity (Ocean Sciences). The new facility for radiogenic isotope analysis will complement recently acquired stable isotope and noble gas mass spectrometers in the department. It will also replace the currently operating, aging TIMS, a VG Sector single collector, which was put into operation in 1986 and has served its purpose well over the past 15 years. The ongoing research projects in Central American volcanism and Late Cretaceous to Holocene sea-level and global climate change will be greatly augmented by the new instrumentation, and will allow a significant increase in the number of samples analyzed. The Central American studies will enhance our understanding of volcanic processes in an active arc system, and in the future may increase our ability to predict volcanic eruptions. The New Jersey drilling program and the biocomplexity research focus significantly on global climate change, and thus have direct impact on an important scientific, social and political problem.***
