Technician Suppport for the MIT Electron Microprobe Facility

9711826 Grove这笔拨款为麻省理工学院的一名技术人员提供了15万美元的三年部分工资支持，用于监督操作和维护，培训新用户并开发使用即将升级的电子显微探针（EAR-9616827）的分析程序。这是IF/EAR计划下的第一阶段技术支持请求。麻省理工学院和伍兹霍尔海洋学研究所（通过他们在麻省理工学院/世界卫生组织海洋学联合方案中的关系）和该区域内的大量教员将受益于该设施的能力。目前资助的和计划中的研究将利用新升级的微探针，包括确定水对俯冲带部分熔融的影响，南喀斯喀特火山的岩石学研究，以及样品的高分辨率结构和矿物学分类，以便为随后的二次离子微探针同位素组成分析确定最佳位置。＊＊＊

9711826 Grove This grant provides $150,000 as three years partial salary support for a technician to oversee operation and maintenance, train new users and develop analytical routines using the soon-to- be upgraded (EAR-9616827) electron microprobes at the Massachusetts Institute of Technology. This is a Phase I request for technical support under the IF/EAR program. A large number of faculty at MIT and Woods Hole Oceanographic Institution (through their relationship in the MIT/WHOI joint program in oceanography) and within the region will benefit from the capabilities of this facility. Currently funded and planned studies that will take advantage of the newly upgraded microprobes include determination of the influence of water on partial melting in subduction zones, petrologic studies of volcanics in the southern Cascades, and high-resolution textural and mineralogic classification of samples in order to identify prime locations for subsequent secondary ion microprobe analysis of isotopic composition. ***
