Acquisition of a 40Ar/39Ar Dating Laboratory at Rutgers University

0130292 Swisher这个NSF仪器和设施奖为罗格斯大学完成“最先进”的40 Ar/39 Ar测年设施所需的设备提供资金，该设施旨在解决地质学，古生物学和人类学中的各种地质年代学问题。 罗格斯大学的设施围绕着一个质量分析仪产品215-50质谱仪，该质谱仪最近随着普林斯顿大学Ar实验室的关闭而获得。 MAP 215-50非常适合40 Ar/39 Ar研究，然而，需要辅助样品提取，气体纯化和计算机系统才能使罗格斯设施完全运行。美国国家科学基金会的这笔资金将提供必要的二氧化碳激光器和电阻炉样品加热系统，以及用于气体净化的自动化、低容量、超低背景提取系统。 Rutgers 40 Ar/39 Ar定年系统所需的样品提取和气体净化系统在大多数情况下都不是现成的;而是必须购买、组装、集成、校准和测试单个组件和部件。因此，除设备外，还需要为扩建、测试和校准阶段的额外技术支助提供资金。 作为NSF和罗格斯大学之间成本分摊的一部分，罗格斯大学承诺为永久博士提供两年的工资和福利支持。水平，研究助理教师的位置，在本提案的任期内的发展和技术援助。 此后，罗格斯大学将继续以50%的水平支持这一职位，剩余的时间将分配给研究计划，合作项目和大学讲师。罗格斯大学还承诺为购买MAP 215-50质谱仪提供资金，超过145，000美元用于研究设施和固定设备的升级和现代化，并承诺为PI提供永久学年工资和福利。监督和发展这些设施 私人侦探正在进行的和提议的研究，研究助理和许多罗特格的教师和学生将立即受益于新仪器的实施。新的Ar设施将作为一种催化剂，汇集了两个独特的工作组罗特格的科学家;一个时标组由教师斯威舍，奥布里，伯格格伦，肯特和米勒，和一个地质古人类学组斯威舍，安东，阿什利，布卢门申，费贝尔和哈里斯。 预计将与罗格斯大学和普林斯顿大学的地质学和人类学教师和学生调查人员进行合作研究，并将继续与其他国家和国际同事进行合作研究。***

0130292Swisher This NSF Instrumentation and Facilities award provides funds for equipment required for the completion of a "state of the art" 40Ar/39Ar dating facility at Rutgers University designed to address a diverse array of geochronological issues in geology, paleontology and anthropology. The Rutgers facility centers around a Mass Analyzer Products 215-50 mass spectrometer recently acquired with the closure of the Princeton University Ar laboratory. The MAP 215-50 is well suited for 40Ar/39Ar research, however, ancillary sample extraction, gas purification, and computer systems were needed to make the Rutgers facility fully operational. NSF funds from this award will provide necessary CO2 laser and resistance furnace sample heating systems, and, an automated, low volume, ultra low background extraction system for gas purification. Sample extraction and gas purification systems necessary for the completion of the Rutgers 40Ar/39Ar dating system are not available, for the most part, as single off the shelf items; rather individual components and parts must be purchased, assembled, integrated calibrated and tested. Thus, in addition to equipment, funding of additional technical support during build-out, testing and calibration phases is also required. As part of cost sharing between NSF and Rutgers University, Rutgers has committed two years salary and benefit support for a permanent Ph.D. level, Research Associate faculty position for development and technical assistance during the tenure of this proposal. Thereafter, Rutgers will continue to support this position at the 50% level, the remaining time to be allotted to research initiatives, collaborative projects and university lectureships. Rutgers has also committed funds for the purchase of the MAP 215-50 mass spectrometer, over $145,000 on upgrades and modernization of research facilities and fixed equipment, and committed permanent academic year salary and benefits for the P.I. to oversee and develop these facilities. Ongoing and proposed research by the P.I., Research Associate and numerous Rutger's faculty and students will benefit immediately from implementation of the new instrumentation. The new Ar facility will serve as a catalyst, bringing together two unique working groups of Rutger's scientists; a timescale group consisting of faculty Swisher, Aubry, Berggren, Kent and Miller, and a geological paleoanthropology group of Swisher, Anton, Ashley, Blumenschine, Feibel, and Harris. Collaborative research with faculty and student investigators in geology and anthropology at Rutgers and Princeton universities is anticipated, as is continued collaborative research with other national and international colleagues. ***
