9725891 Baldwin This grant provides two years partial salary support for a technician to oversee operation and maintenance and to provide training to new users of the University of Arizona Noble gas mass spectrometry laboratory. This technical position has been and will continue to be, shared between Suzanne Baldwin (Dept of Geosciences) and Timothy Swindle (Dept of Planetary Sciences). Given the primary source of research support of the latter, NASA will co-fund a portion of the technician's salary. The Noble gas group at the University of Arizona has traditionally focused on terrestrial geochronology and thermochronology using the 40-Ar/39-Ar technique for studies in tectonics and cosmochemistry and planetary scale chronology using the 129-I/129-Xe system. More recently, with the addition to the faculty of Marek Zreda, they have expanded into the 3-He/4-He system and the use of 21Ne as both tracers and environmental proxies of hydrologic systems. The new arrival of a second Noble gas mass spectrometer in this laboratory (funded through the W. M. Keck Foundation) will add significantly to the research capabilities of this group and to the duties of the technician. ***

9725891 Baldwin 这笔赠款为技术人员提供两年的部分工资支持，以监督操作和维护，并为亚利桑那大学惰性气体质谱实验室的新用户提供培训。 这一技术职位已经并将继续由 Suzanne Baldwin（地球科学系）和 Timothy Swindle（行星科学系）共同承担。 鉴于后者的研究支持的主要来源，美国宇航局将共同资助技术人员的部分工资。 亚利桑那大学的稀有气体小组传统上专注于陆地地质年代学和热年代学，使用 40-Ar/39-Ar 技术研究构造学和宇宙化学以及使用 129-I/129-Xe 系统的行星尺度年代学。 最近，随着 Marek Zreda 教师的加入，他们已扩展到 3-He/4-He 系统以及使用 21Ne 作为水文系统的示踪剂和环境代理。 该实验室新引进的第二台惰性气体质谱仪（由 W. M. Keck 基金会资助）将显着增强该小组的研究能力和技术人员的职责。 ***
