This award provides one-half the funding required to upgrade an old but functional electron microprobe operated by the Department of Geological Sciences at the University of Maine. The University is committed to providing the remaining funds required for the upgrade. The electron microprobe is a standard instrument of choice for in-situ quantitative analysis of the elemental composition of solids with a spatial resolution equal to several microns or better. The University of Maine operates the only such instrument in the state. The current instrument is old but worthy of repairs and improvements. This upgrade will add an energy dispersive X- ray spectrometer system and will modernize the power supply and other key electronic components at much less cost than a new instrument. The upgraded microprobe will continue to service faculty and student research projects at the University of Maine and to be available to outside researchers as well.

该奖项提供升级所需资金的一半 一个旧的，但功能的电子显微探针操作的 缅因州大学地质科学系。的 大学承诺提供所需的剩余资金 为了升级 电子探针是一种标准的仪器选择 用于现场定量分析的元素组成， 空间分辨率等于几微米的固体，或 好多了缅因州大学是唯一一所这样的仪器 在状态现在的仪器很旧，但值得修理 和改进.这次升级将增加一个能量分散X- 射线光谱仪系统，并将现代化的电源， 其他关键电子元件的成本远低于新的 仪器升级后的微探针将继续服务 缅因州大学的师生研究项目 也可以供外部研究人员使用。
