Upgrade of Research Equipment: Refurbishing the Thermal Ionization Mass Spectrometer at the University of Colorado, Boulder

该提案寻求约10.6万美元的资金来翻新Finnigan-MAT 261热电离质谱仪（TIMS）。主要需要的升级是一个现代化的计算机系统以及接口卡和软件来控制仪器。制造商实质上不再支持该仪器，所以第三方供应商？S的产品将被购买。另外还需要两个替换灯丝电源和离子源高压电源。还要求提供安装费。TIMS设施赞助部门内和外部用户，并提供一定程度的培训和样品处理协助。设备的采购和安装将允许pi保持21年的TIMS服务。pi已经完成了超过20,000次测量-主要是Sr， Nd, Pb, Rb, Sr, Pb， Sm和Nd浓度/同位素。该部门（地质科学）和环境科学合作研究所（CIRES）支持一个综合仪器开发设施（IIDF），包括电子、机械加工和维修专业知识。PI拥有充足的EAR研究资金，并从事流纹岩成因、层状花岗岩形成、硅屑沉积物物源和古水文研究。升级后的优点包括能够长时间收集数据，能够以电子方式分析数据，能够以更自动化的方式运行仪器，能够将数据采集系统联网，从而使数据采集系统更加灵活。可以避免打印输出和人工数据输入，并且不必购买纸张，磁盘和其他消耗品而节省成本。仪器和相关实验室支持学生，CIRES，科罗拉多大学和外部研究人员。PI培养了许多研究生，雇用和培训本科生，并与其他几十所大学和联邦机构建立了合作关系。PI目前支持三名博士生和另外四名地质学研究生在TIMS实验室工作。结果定期公布。***

Primary amongst the needed upgrades is a modern computer system along with interface cards and software to control the instrument. The manufacturer in essence no longer supports this instrument so a third party vendor?s products will be purchased. Also requested are two replacement filament power supplies and ion source high voltage supply. Installation costs are also requested. The TIMS facility sponsors in-department and outside users and provides a level of training and sample processing assistance. The equipment acquisition and installation will allow the PIs to keep a 21 year old TIMS in service. The PIs have completed over 20,000 measurements - mostly Sr, Nd, Pb, Rb, Sr, Pb, Sm and Nd concentrations/isotopes. The department (Geological Sciences) and institute, the Cooperative Institute for Research in Environmental Sciences (CIRES), support an Integrated Instrument Development Facility (IIDF) consisting of electronics, machining and repair expertise. The PI has ample EAR research funding and works on rhyolite genesis, epizonal granite formation, siliciclastic sediment provenance, and paleohydrology. The advantages of the upgrade include being able to collect data over longer periods of time, being able to analyze data electronically, the ability to run the instrument in a more automated fashion, the ability to network the data acquisition system so that ?hard? printouts and manual data entry can be avoided, and the cost savings in not having to purchase paper, diskettes and other consumables. The instrument and associated laboratory support students, CIRES, University of Colorado and outside researchers. The PI has trained numerous graduate students, employed and trained undergraduates, and developed collaborations at dozens of other universities and federal agencies. The PI currently supports three PhD students and has four other Geology graduate students working in the TIMS lab. Results are regularly published.***
