MRI: Development of an Electron Microprobe Teaching & Research Facility

这笔赠款通过重大研究仪器(MRI)计划提供部分支持，用于升级夏威夷大学希洛分校地质系现有的ARL-SEMQ电子微探头(EMP)。这台电磁脉冲最近由美国地质勘探局捐赠给美国地质调查局，并已升级为基于计算机的现代控制和数据采集系统。这个支架将取代电子枪电源(现在已有20年历史)、背向散射成像系统和微探头内的光学反射镜。此外，由于教学和教育是该实验室的一项重要任务，资金将用于发展远程操作能力。这将允许演示电磁脉冲技术在当前的课程和研讨会中使用，并为当地高中制作推广计划。额外资金将用于购买碳涂层以及光学显微镜和图像分析系统。在UH-Hilo拥有可操作的现代化电子显微镜设施将极大地增强他们吸引和留住理科学生的能力。特别是，夏威夷和太平洋岛民学生占学生总数的很大比例。附近美国地质勘探局夏威夷火山天文台(HVO)的研究人员也将使用该探测器对玄武岩熔岩进行初步的定量化学和结构分析。***

0116904HonThis grant, made through the Major Research Instrumentation (MRI) Program, provides partial support to upgrade an existing ARL-SEMQ electron microprobe (EMP) in the Geology Department at the University of Hawaii-Hilo. This EMP was recently donated to the Department by the USGS and has since been upgraded with modern PC-based control and data acquisition systems. This support will replace the electron gun power supply (now 20 years old), the back-scatter imaging system, and the optical mirrors within the microprobe. In addition, as teaching and education are an important mission of this laboratory, funds will be used to develop a remote operating capability. This will allow demonstrations of EMP techniques for use in current courses, workshops and to produce outreach programs for local high schools. Additional funds will be used for the purchase of a carbon coater and an optical microscope and image analysis system. Having an operational and modern electron microscopy facility at UH-Hilo will greatly enhance their ability to attract and retain students in the sciences. In particular, Hawaiian and Pacific Islander students make up a large proportion of the student body. Researchers at the nearby USGS Hawaiian Volcanological Observatory (HVO) will also have access to the probe for initial quantitative chemical and textural analysis of basaltic lavas. ***
