This project is to upgrade the Earth & Environmental Science's Electron Microprobe Laboratory (EMPL) housing a Cameca SX-100 Electron Probe Microanalyzer at Rensselaer Polytechnic Institute (RPI). The upgrade involves the installation of a new computer workstation running Probe for EPMA and Probe Image interfaced with the instrument. This upgrade was justified on the basis of three main criteria: First, examples were provided of major limitations imposed by the current vendor-supplied software package (Cameca's Peak Sight) that may be overcome using software available from Probe Software, Inc including (1) new algorithms to improve minimum detection limits, precision, and accuracy; (2) superior time-dependent intensity corrections; and (3) improved X-ray mapping capabilities. Second, a description was presented of ongoing and future projects that have compelling scientific merit and require characterization using a state-of-the-art electron microprobe. Third, this facility has had an excellent track record of high quality science with current instrumentation, a successful and sustainable maintenance and administration plan, numerous collaborative research efforts, and a highly diverse user base. An upgraded Electron Microprobe Laboratory at RPI will benefit both the larger Rensselaer Community and the broader Upstate New York/New England Region by enhancing current capabilities as a regional facility. The EMPL has been and will continue to be open to the public along with undergraduates, graduate students, post-docs, research faculty, and professors at Rensselaer and elsewhere. In addition to providing analyses free of charge to undergraduates completing various projects, this facility participates annually in the ExxonMobil Bernard Harris Summer Science Camp, a free two-week program for fifty middle school students (grades 6-8) from the New York Capital Region designed to instill a life-long interest in math and science. This upgrade will greatly enhance the learning experiences of students, visitors, and new users alike thanks to the fully-integrated, user-friendly nature of Probe for EPMA which visually emphasizes important considerations (background models, time-dependent intensity corrections, wave scans, etc.).

该项目旨在升级地球与环境科学的电子微探针实验室（EMPL），该实验室（EMPL）容纳了坎塞勒理工学院（RPI）的嵌嵌小孔SX-100电子探针微分析仪。升级涉及安装新的计算机工作站运行探测器，并与仪器连接的探测图像。根据三个主要标准，这项升级是合理的：首先，提供了当前供应商提供的软件包（Cameca's Peave）所施加的主要限制，这些软件包（Cameca's Peave）可以使用Proipe Software，Inc（包括（1）新算法的软件（包括（1）新算法）以提高最小检测限制，精度和精度； （2）较高的时间依赖性强度校正； （3）提高X射线映射功能。其次，描述了正在进行的和未来的项目，这些项目具有令人信服的科学功绩，并需要使用最先进的电子微探针进行表征。第三，该设施具有高质量科学的出色记录，并具有当前的仪器，成功，可持续的维护和管理计划，众多协作研究工作以及高度多样化的用户群。 RPI升级的电子微探针实验室将通过增强当前作为区域设施的当前能力来使较大的伦斯勒社区和更广泛的纽约州北部/新英格兰地区受益。 EMPL曾经并将继续向公众开放，本科生，研究生，博士后，研究教师以及伦斯勒和其他地方的教授。除了免费提供分析以完成各种项目的本科生外，该设施每年还参加Exxonmobil Bernard Harris Summer Science Camp，这是一个免费的为期两周的中学生（6至8年级）的为期两周的免费计划，该计划旨在灌输对数学和科学的终身兴趣。由于EPMA的完全集成，用户友好的探针性质，该升级将大大增强学生，访客和新用户的学习经历，而这些探针的性质在视觉上强调了重要的考虑因素（背景模型，与时间相关的强度校正，波浪扫描等）。
