0107175FerrySupport is requested for acquisition of a new automation system for the JEOL JXA-8600 electron microprobe in the Department of Earth and Planetary Sciences at Johns Hopkins University. The instrument is 13 years old and a number of components are failing and unreliable including the memory devices, the LSI 11/73 computer, the energy dispersive spectrometer (EDS), and the stage motor drives. In addition, because the operating system, EDS, and computers are outdated, the instrument is incapable of a number of important functions that modern microprobes can perform such as light element detection by EDS (B through F); position-tagged spectroscopy; simultaneous collection of images and compositional data; integrated data collection, data reduction, and image processing with the same computer; and rapid exchange of images and analytical data between the microprobe and external computers. Support is also requested to replace the aging and dysfunctional carbon coater in the microprobe laboratory. An upgraded electron microprobe would be used in a wide variety of research projects including studies in metamorphic petrology, igneous petrology, mineralogy, crystallography, sedimentology, geochemistry, geochronology, radioactive waste disposal and remediation, materials science, and medicine. An electron microprobe, operating at top performance, will continue to play a key role in training the next generation of Earth scientists by serving as a principal research instrument for students at the undergraduate, graduate, and postdoctoral levels. The Department of Earth and Planetary Sciences and the School of Arts and Sciences have pledged to cover 16.7% and 33.3% of the cost of the acquisition, respectively. NSF is requested to cover the remaining 50%. The Department will continue to support the electron microprobe facility by paying the salary and benefits of the technician. The School of Arts and Sciences will continue to support the facility with an annual block contribution.***

0107175FerrySupport公司被要求为约翰霍普金斯大学地球和行星科学系的JEOL JXA-8600电子显微探针采购一套新的自动化系统。该仪器已有13年的历史，包括存储设备、LSI 11/73计算机、能量色散光谱仪（EDS）和级电机驱动器在内的许多部件都出现了故障和不可靠。此外，由于操作系统、能谱仪和计算机已经过时，该仪器无法实现现代微探针可以执行的一些重要功能，例如能谱仪的轻元素检测（B到F）；position-tagged光谱学;同时采集图像和成分数据；在同一台计算机上集成数据采集、数据简化和图像处理；在微探针和外部计算机之间快速交换图像和分析数据。还要求支持更换微探针实验室老化和功能失调的碳涂层机。升级后的电子探针将广泛用于各种研究项目，包括变质岩石学、火成岩岩石学、矿物学、晶体学、沉积学、地球化学、地质年代学、放射性废物处理和修复、材料科学和医学。作为本科生、研究生和博士后的主要研究仪器，以最高性能运行的电子显微探针将继续在培养下一代地球科学家方面发挥关键作用。地球与行星科学系和艺术与科学学院承诺分别承担此次收购成本的16.7%和33.3%。国家科学基金会被要求支付剩余的50%。该部将继续通过支付技术人员的薪金和福利来支持电子显微探针设施。文理学院将继续为该设施提供年度捐款
