Acquisition of an Electron Microprobe

该合同将允许夏威夷大学（UH）购买一种新的、最先进的电子微探针（EMP），以支持广泛的陆地、海底和地外主题的研究和教育。我们目前的Cameca SX-50已经使用了15年，缺乏重要的功能（例如，自动对焦和大面积晶体），这是提高我们工作质量和数量所需要的，也是我们可以探索火山学、实验岩石学、海洋地质学、行星科学、海洋学和材料科学的问题的本质。现代EMP是我们微分析设备的重要组成部分（新的Cameca ims 1280离子探针，带EBSD的SEM和激光烧蚀ICPMS）。使用这些仪器的研究人员之间的协同作用将加强这些实验室的运作。该提案的资金包括EAR-IF和OCE-MGG项目的联合支持，来自UH的30万美元配套资金，以及向NASA申请的40万美元行星研究资金。为了维持该设施的长期财政稳定，UH提供经理工资的50%。用户费用将支付管理人员工资的25%（其他25%来自补助金），并支付供应费用和与EMP供应商签订的预防性维护合同。夏威夷大学拥有27年成功运行电磁脉冲设施的记录。这个新的电磁脉冲将成为本科生和研究生的研究工具。他们将学习这一精密仪器的理论和实践方面的知识。EMP将在休斯敦大学的课程中向其他学生介绍，并通过互联网向当地公立学校的学生展示，以及在校园参观期间，特别是在我们的开放日。

This award will permit the University of Hawaii (UH) to purchase a new, state-of-the-art electron microprobe (EMP) to support research and education in a broad range of terrestrial, submarine and extraterrestrial topics. Our current Cameca SX-50 is 15 years old and lacks important features (e.g., auto focus and large area crystals) that are needed to improve the quality and quantity of our work, and to expand the nature of the problems we can explore volcanology, experimental petrology, marine geology, planetary sciences, oceanography and material science. A modern EMP is an essential component to our micro-analytical facilities (a new Cameca ims 1280 ion probe, SEM with EBSD and laser ablation ICPMS). The synergy between the researchers using these instruments will enhance the operation of these labs.The funding package for this proposal involves joint support by EAR-IF and OCE-MGG programs, $300,000 in matching funds from UH, and a $400,000 request to NASA for planetary research. In order to maintain a long-term fiscal stability for the facility, UH is providing 50% of the manager's salary. User fees will cover 25% of the manager's salary (other 25% from grants) and cover costs for supplies and a preventive maintenance contract with the EMP vendor. The University of Hawaii has a 27-year record of successfully operating an EMP facility.This new EMP will be a research tool for undergraduate and graduate students. They will be taught the theory and practical aspects of this sophisticated instrument. The EMP will be introduced to other students in UH courses and at demonstrations for local public school students via the internet and during on-campus visits, especially at our open house.
