9707054 Wendlandt This grant provides $48,962 as one-half support of the costs of upgrading the Cameca MBX electron microprobe (EMP) at the Colorado School of Mines with a PC-based automated instrument interface, a digital imaging system for analyses of backscattered electron images and crystals permitting light element analyses (i.e. Li, B). This upgrade is a significant improvement over the current and original (vintage 1980) DEC PDP-11 based computer control system, which is no longer supported by the manufacturer. PC-automation and digital image analysis will benefit a variety research programs currently utilizing the EMP for quantitative geochemical analysis including studies of the petrogenesis of continental rift volcanics, elucidation of the driving forces behind dolomitization of reef carbonates, studies of the phase equilibria of carbonate systems, and metallurgical studies. Furthermore, this upgrade will provide students with training on software packages that are the current standard at larger research institutions and laboratories. ***

小行星9707054 这笔赠款提供了48 962美元，作为对科罗拉多矿业学院Cameca MBX电子微探针（EMP）升级费用的一半支持，该电子微探针配备了基于PC的自动仪器接口、用于分析背散射电子图像的数字成像系统和允许进行轻元素分析的晶体（即Li，B）。 这次升级是对当前和原始（1980年）DEC PDP-11计算机控制系统的重大改进，该系统不再由制造商支持。 PC自动化和数字图像分析将有利于目前利用EMP进行定量地球化学分析的各种研究计划，包括大陆裂谷火山岩的岩石成因研究，阐明礁碳酸盐岩化背后的驱动力，碳酸盐体系的相平衡研究和冶金研究。 此外，这一升级将为学生提供有关软件包的培训，这些软件包是大型研究机构和实验室的现行标准。 ***
