Acquisition of a Multicollector Thermal Ionization Mass Spectrometer

罗格斯大学地质科学系将用美国国家科学基金会和罗格斯大学联合提供的资金购买一台新的多收集器质谱仪。该仪器对于目前由美国国家科学基金会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/边缘/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）。新的放射性成因同位素分析设备将补充该部门最近获得的稳定同位素和惰性气体质谱仪。它还将取代目前运行的老化的TIMS，即VG Sector单收集器，该收集器于1986年投入使用，在过去的15年里一直发挥着良好的作用。正在进行的中美洲火山作用、晚白垩世到全新世海平面和全球气候变化的研究项目将被新的仪器大大增强，并将允许分析的样本数量显著增加。中美洲的研究将加强我们对活动弧系统中火山过程的理解，并可能在未来提高我们预测火山爆发的能力。新泽西钻探项目和生物复杂性研究的重点是全球气候变化，因此对一个重要的科学、社会和政治问题有直接影响

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.***
