Technician Support: Noble Gas Mass Spectrometry Laboratory

小行星9725891 这项赠款为一名技术员提供两年的部分薪金支助，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。 这个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）分享。 鉴于后者的研究支持的主要来源，美国航天局将共同资助技术人员的工资的一部分。 亚利桑那大学的惰性气体小组传统上侧重于使用40-Ar/39-Ar技术进行大地年代学和热年代学研究，以研究构造和宇宙化学，并使用129-I/129-Ar系统进行行星规模的年代学研究。 最近，随着Marek Zreda教授的加入，他们已经扩展到3-He/4-He系统，并使用21 Ne作为水文系统的示踪剂和环境代理。 第二台稀有气体质谱仪（由W。 M.凯克基金会）将大大增加这个小组的研究能力和技术人员的职责。 ***

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. ***
