Phase II Technician Support: Syracuse University Noble Gas Isotope Research Laboratory (SUNGIRL)

该合同将由美国国家科学基金会仪器和设施部门提供为期两年的支持，以分担锡拉丘兹大学惰性气体同位素研究实验室（SUNGIRL）一名技术人员职位的费用。该职位的费用将与雪城大学的捐款分担。SUNGIRL由1)一台Micromass 5400稀有气体质谱仪和自动萃取线组成，用于40Ar/39Ar热年代学；2)一台四极杆质谱仪和自动萃取线，用于He分析，并结合磷灰石(U-Th)/He定年。每条提取线都使用双真空电阻炉和二氧化碳激光系统来排出矿物和岩石。用于5400惰性气体质谱仪的准分子激光系统正在建设中。一旦完全投入使用，它将扩展SUNGIRL的分析能力，包括对厚剖面矿物的原位40Ar/39Ar分析。在pi的总体指导下，技术员负责实验室的日常管理和运营，包括设备的维护，设计修改和惰性气体质谱技术的开发。

EAR-0447305BaldwinThis award will provide two years of support from NSF Instrumentation and Facilities to share the costs of a technician's position in the Syracuse University Noble Gas Isotope Research Laboratory (SUNGIRL). The position will be cost shared with contributions from Syracuse University. SUNGIRL consists of 1) a Micromass 5400 noble gas mass spectrometer and automated extraction line used for 40Ar/39Ar thermochronology, and 2) a quadrupole mass spectrometer and automated extraction line used for He analysis in conjunction with (U-Th)/He dating of apatite. Each extraction line utilizes a double-vacuum resistance furnace and a CO2 laser system for outgassing minerals and rocks. An excimer laser system is under construction for use with the 5400 noble gas mass spectrometer. Once fully commissioned it will expand SUNGIRL's analytical capabilities to include in situ 40Ar/39Ar analysis of minerals in thick sections. Under the general direction of the PIs, the technician is responsible for the day-to-day management and operation of the laboratory including maintenance of equipment, design modifications, and development of noble gas mass spectrometric techniques.
