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. ***

1028102Ripley 该奖项在 24 个月内提供总计 300,000 美元的资金，用于为稳定同位素研究设施 (SIRF) 购买两台气源同位素比质谱仪 (IRMS) 系统。这些仪器将取代目前出现故障的仪器。这些仪器将用于岩石学和矿石成因、地球微生物学、行星过程、水-岩石相互作用、环境评估、大气科学和考古学。该仪器将为化学、生物学、地理/大气科学、考古学、公共与环境事务学院以及管理 SIRF 的地质科学系的教师提供支持。此外，外部用户（过去三年约 80 名）也使用过该设施。 SF6 分析需要能够同时测量四个离子束的仪器。需要使用更标准的仪器来进行氧、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。学生使用率也很高。 SIRF 为学生提供实践培训。培训包括样品制备和仪器操作。 PI 和联合 PI 管理 SIRF 已超过 20 年。两位 Pi 都在为代表性不足的研究生提供建议方面拥有深厚的背景。这些仪器将安置在现有的 SIRF 空间内。该设施有两名全职技术研究人员。技术人员的工资、用品和维护来自赠款支持和外部用户费用。 ***
