Acquistion of a New Automation System for an Electron Microprobe

0107175约翰霍普金斯大学地球与行星科学系JEOL JXA-8600电子微探针的新自动化系统的采购需要FerrySupport。 该仪器已使用13年，许多组件出现故障且不可靠，包括存储设备、LSI 11/73计算机、能量色散光谱仪（EDS）和载物台电机驱动器。 此外，由于操作系统、EDS和计算机已经过时，该仪器不能实现现代微探针可以执行的许多重要功能，例如通过EDS进行的轻元素检测（B至F）;位置标记光谱学;同时收集图像和组成数据;用同一计算机集成数据收集、数据简化和图像处理;以及在微探针和外部计算机之间快速交换图像和分析数据。 还要求提供支助，以更换微探针实验室中老化和功能失调的碳涂层器。 升级后的电子探针将用于各种各样的研究项目，包括变质岩石学、火成岩学、矿物学、结晶学、沉积学、地球化学、地质年代学、放射性废物处理和补救、材料科学和医学的研究。 一个电子微探针，在最高性能的操作，将继续发挥关键作用，在培养下一代地球科学家作为一个主要的研究工具，为学生在本科，研究生和博士后水平。 地球和行星科学系以及艺术与科学学院已承诺分别支付收购成本的16.7%和33.3%。 NSF负责剩下的50%。 该部将继续支助电子显微探针设施，支付技术员的薪金和福利。 艺术和科学学院将继续支持该设施与年度块贡献。

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.***
