Upgrading of the UCSB Multi-Collector Thermal Ionization Mass Spectrometer

该奖项提供了加州大学圣巴巴拉分校地质科学系热电离源质谱仪现代化所需资金的一半。该机构承诺提供该项目所需的剩余资金。需要升级的研究项目包括使用铀铅同位素对非常小的样品进行地质年代学，对地幔过程进行示踪研究，以及对海洋碳酸盐物质进行铀不平衡定年研究。仪器的升级将提高其分析极少量样品的能力，这是研究的基本要求。* * *

9316951 Mattinson This award provides one-half the funding needed to modernize a thermal ionization source mass spectrometer operated in the Department of Geological Sciences at the University of California at Santa Barbara. The institution is committed to providing the remaining funds necessary for the project. The research projects necessitating the upgrade include geochronology of very small samples using uranium-lead isotopes, tracer studies of mantle processes, and uranium disequilibrium dating studies of marine carbonate materials. The upgrades to the instrument will enhance its ability to analyze very small amounts of samples, a basic requirement of the research. ***
