项目摘要

1028102RipleyThis award provides $300,000 in total funding over 24 months to acquire two gas-source isotope ratio mass spectrometers (IRMS) systems for the Stable Isotope Research Facility (SIRF). The instruments will replace current failing ones. The instruments will be used for petrology and ore genesis, geomicrobiology, planetary processes, water-rock interaction, environmental assessment, atmospheric science and archaeology. The instrumentation will support faculty from Chemistry, Biology, Geography/Atmospheric Sciences, Archaeology and the School of Public and Environmental Affairs in addition to the Department of Geological Sciences which manages the SIRF. In addition, outsider users (~ 80 in the past three years) have utilized the facility. An instrument capable of four ion beams simultaneous measurement is requested for SF6 analysis. A more standard instrument is requested which will be used for oxygen, carbon, and nitrogen isotope analysis. The SIRF has users both at Indiana University and outside institutions. Student use is also high. The SIRF provides hands-on training for students. Training includes sample prep and instrument operation. The PI and co-PI have managed the SIRF for more than 20 years. Both Pis have a strong background in advising underrepresented graduate students. The instruments will be housed in the existing SIRF space. The facility has two full-time technical researchers. Technician salary, supplies and maintenance come from grant support and external user fees. ***

1028102RipleyThis奖在24个月内提供300,000美元的总资金，以获取两个稳定同位素研究设施（SIRF）的两个气源同位素比率质谱器（IRMS）系统。这些仪器将替换当前失败的仪器。这些仪器将用于岩石学和矿石创世纪，地球生物学，行星过程，水摇滚相互作用，环境评估，大气科学和考古学。该仪器将支持化学，生物学，地理/大气科学，考古学和公共与环境事务学院的教师，除了管理SIRF的地质科学系。此外，局外用户（过去三年中约有80个）利用了该设施。请求同时测量四个离子光束的仪器进行SF6分析。请求一种更标准的仪器，该仪器将用于氧，碳和氮同位素分析。 SIRF在印第安纳大学和外部机构都有用户。学生使用也很高。 SIRF为学生提供动手培训。培训包括样品准备和仪器操作。 PI和Co-Pi已管理SIRF已有20多年了。这两个PI在为人数不足的研究生提供建议方面都有很强的背景。这些仪器将安置在现有的SIRF空间中。该设施有两名全日制技术研究人员。技术人员的薪水，物资和维护来自赠款支持和外部用户费用。 ***
