Technician Support: UCLA Thermal Ionization Mass Spectrometry Facility (Phase II)

小行星9633808 这笔赠款提供了10万美元，作为技术人员工资支助的两年部分支助，该技术人员将负责加州大学洛杉矶分校热电离质谱设施和相关洁净室的运营、维护和监督。 该合同是IF计划下的第二阶段技术支持提案，第一阶段技术支持为期三年，于1996年7月31日到期。 实验室经理将操作和维护两个TIMS，一个VG Sector 54- 30（带多个收集器）和一个升级的VG 54 E。 Sector 54仪器专用于分析Pb、Sr和Nd同位素，而54 E仪器则用于同位素稀释测量和技术开发。 在该奖项有效期内进行的具体研究将包括大陆玄武岩的Th同位素研究，作为其地幔来源的指示，使用宇宙成因放射性核素对地质样品进行暴露年龄测定，（即14-C，36-Cl，26-Al和10-Be）和Sr同位素分带研究，探讨岩浆分异的时间尺度。 ***

9633808 Reid This grant provides $100,000 as two years partial support of a technician's salary support who would be responsible for operations, maintenance and oversight of the UCLA thermal ionization mass spectrometry facility and associated clean rooms. This award is a Phase II technician support proposal under the IF program and follows three years of Phase I technician support which expires on 7/31/96. The lab manager will operate and maintain two TIMS housed at UCLA, a VG Sector 54- 30 with multiple collectors and an upgraded VG54E. The Sector 54 instrument is dedicated to analyses of Pb, Sr and Nd isotopes while the 54E is reserved for isotope dilution measurements and technique development. Specific research to be undertaken during the duration of this award will include Th isotope studies of continental basalts as indicators of their mantle source, exposure age dating of geologic samples using cosmogenic radionuclides (i.e. 14-C, 36-Cl, 26-Al and 10-Be) and Sr isotope zonation studies of individual phenocrysts from arc volcanics to investigate the time scales of magmatic differentiation. ***
