Acquisition of an Excimer Laser System for Syracuse University Noble Gas Isotope Research Laboratory (SUNGIRL)

该赠款为锡拉丘兹大学惰性气体同位素研究实验室（SUNGIRL）购买准分子激光系统提供资金。 SUNGIRL目前包括：1）Micromass 5400惰性气体质谱仪和自动提取线，以及2）四极质谱仪和自动提取线，用于He分析以及辅助相的（U-Th）/He定年。每条提取线都利用自己的双真空电阻炉对岩石和矿物进行脱气。 一个共享的CO2激光系统也可以用于与（U-Th）/He和40 Ar/39 Ar热年代学相结合的矿物颗粒除气（包括通量监测器）。锡拉丘兹大学的热年代学研究小组的重点是确定地壳岩石的压力-温度-时间-变形（P-T-t-D）演化和量化地质过程的速率。 准分子激光系统将通过使用尖端技术进行现场分析，加强研究生和本科生的教育和培训。 使用拟议的激光系统获得的数据将：1）在PI教授的两门研究生和高级本科课程（热年代学和微观结构分析）中突出显示，2）在国家和国际会议上提出，3）在地球科学文献中发表。 SUNGIRL通过NSF REU赠款雇用本科生，是锡拉丘兹大学地球科学技术和妇女科学技术的展示实验室。 该激光系统将由锡拉丘兹大学的教师、研究人员、博士后研究员、研究生和本科生以及访问研究人员使用。锡拉丘兹大学将承担激光系统30%的费用。

EAR-0345822BaldwinThis grant provides funding for acquisition of an excimer laser system for the Syracuse University Noble Gas Isotope Research Laboratory (SUNGIRL). SUNGIRL currently consists of: 1) a Micromass 5400 noble gas mass spectrometer and automated extraction line, and 2) a quadrupole mass spectrometer and automated extraction line for He analysis in conjunction with (U-Th)/He dating of accessory phases. Each extraction line utilizes its own double-vacuum resistance furnace for out-gassing rocks and minerals. A shared CO2 laser system can also be used for out-gassing mineral grains (including flux monitors) in conjunction with (U-Th)/He and 40Ar/39Ar thermochronology. The focus of the thermochronology research group at Syracuse University is on determining the pressure-temperature-time-deformation (P-T-t-D) evolution of crustal terranes and quantifying rates of geologic processes. The excimer laser system will enhance graduate and undergraduate student education and training through the use of cutting-edge technology for in situ analysis. Data obtained using the proposed laser system will: 1) be highlighted in two graduate and upper-level undergraduate courses (Thermochronology and Microstructural Analysis) taught by the PIs, 2) be presented at national and international meetings, and 3) be published in the Earth Science literature. SUNGIRL employs undergraduate students through NSF REU grants and is a showcase laboratory at Syracuse University for technology in the Earth Sciences, and for women in science and technology. The laser system will be used by Syracuse University faculty, researchers, post-doctoral fellows, graduate and undergraduate students, and visiting researchers. Syracuse University will contribute 30% towards the cost of the laser system.
