MRI: Development of an Electron Microprobe Teaching & Research Facility

[01:16904]这项拨款通过主要研究仪器（MRI）计划获得，为夏威夷大学希洛分校地质系现有的ARL-SEMQ电子显微探针（EMP）的升级提供部分支持。这个电磁脉冲器最近由美国地质勘探局捐赠给该部门，并已升级为现代基于个人电脑的控制和数据采集系统。这种支持将取代已有20年历史的电子枪电源、后向散射成像系统和微探针内的光学反射镜。此外，由于教学和教育是该实验室的一项重要任务，资金将用于开发远程操作能力。这将允许在目前的课程、讲习班中示范电磁脉冲技术，并为当地高中制作推广方案。额外的资金将用于购买一个碳涂层机和一个光学显微镜和图像分析系统。在UH-Hilo拥有一个可操作的现代电子显微镜设备将大大提高他们吸引和留住科学学生的能力。特别是夏威夷和太平洋岛民学生占学生总数的很大比例。附近的美国地质勘探局夏威夷火山观测站（HVO）的研究人员也将可以使用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. ***
