Data acquisition and analysis system for electron probe micro-analyzer

需要一种新的数据采集和分析系统来升级微分析实验室的Cameca SX-100电子探针微分析仪（EPMA）。EPMA提供主要到微量元素（10s ppm）的原位化学分析，空间分辨率高达1um3。EPMA化学成分数据具有很高的精度（< 5%，主要元素；<20%痕量）和准确性。迫切需要新系统来取代在过时的UNIX UltraSparc I工作站上运行的老化的、已有20年历史的系统，该系统的替换部件已不再可用。EPMA上原有EDS系统的探测器已经失去了灵敏度和光谱分辨率，无法再提供我们研究项目所需的准确和精确的结果。这些升级对于EPMA的运行至关重要，并且将大大增强和扩展EPMA的能力，超越其原始水平，为我们的研究项目提供关键的分析能力。

A new data acquisition and analysis system is requested to upgrade a Cameca SX-100 electron probe micro-analyzer (EPMA) at the Laboratoire de microanalyse. The EPMA provides in situ chemical analyses for major to trace elements (10s ppm) with a spatial resolution up to 1um3. The EPMA chemical composition data has a high precision (< 5%, major elements; <20% traces), and accuracy. The new system is urgently required to replace the aging, 20-year old system running on an outdated UNIX UltraSparc I workstation, for which replacement parts are no longer available. The detector of the original EDS system on the EPMA has lost sensitivity and spectral resolution and cannot provide anymore the accurate and precise results required by our research programs. These upgrades are critical and urgent to operate the EPMA, and will significantly enhance and extend the EPMA capabilities beyond their original level, providing critical analytical capabilities to carry our research programs.
