We are requesting a high-throughput energy dispersive X-ray spectrometry (EDS) detector for the plasma focused ion beam scanning electron microscope (PFIB) recently purchased by McMaster University, the first such tool in Canada. This analytical attachment is essential for X-ray analysis and mapping in order to identify the chemical composition of sample and to reconstruct chemical maps in 3-Dimensions during serial sectioning with the PFIB. This tool will also enable the chemical identification of the areas of interest for subsequent sectioning and milling using the spectroscopic chemical information as a guide to the researcher. The tool is also indispensable for the identification of phases in materials that need to be analysed subsequently in the transmission electron microscope and the 3D atom probe. Several research groups will benefit from the requested instrument. Projects include the analysis of the 3D structure of Li battery materials, the analysis of cracks in steam generator materials used in nuclear power plants, the development of light emitting diodes, the analysis of composite concrete materials, the analysis of the oldest geological materials on earth, lunar samples, photonic structures and metamaterials. The tools is urgently required to enable the correct identification of materials, the correct reconstruction of materials in 3-dimensions taking advantage of the unique high-throughput milling capabilities of the Plasma FIB. The tool will also enable faster feedback on their samples, more reliable interpretation of results and faster progress in research, leading to more relevant and internationally competitive publication. Beyond the 7 research groups with their 47 HQP, their 18 collaborators in the proposed projects (and their HQP) involved in the research and industrial partners relying on this tool, the instrument will be located at the Canadian Centre for Electron Microscopy (CCEM), a truly open-access facility supported by the Major Science Initiative with oversight from a user's group who highlighted the need for this tool and this application. The Centre supports over 430 users annually who use multiple tools in the facility, including the PFIB. They will also use this HT-EDS instrumentation for their work. The CCEM facility operates all instrument tools with dedicated technical staff who train users on the proper operation of all instruments it operates, thus ensuring that the equipment will be used widely and effectively.

我们要求麦克马斯特大学（McMaster University）购买的高通量分散X射线光谱法（EDS）检测器（EDS）检测器（PFIB）是由加拿大第一个工具麦克马斯特大学购买的。 该分析附件对于X射线分析和映射至关重要，以确定样品的化学组成并在与PFIB串行分段期间重建三维的化学图。该工具还将能够使用光谱化学信息作为研究人员的指导，以化学识别感兴趣区域的后续切片和铣削。该工具对于鉴定需要随后在透射电子显微镜和3D原子探针中进行分析的材料中的相位也是必不可少的。几个研究小组将从请求的工具中受益。项目包括对LI电池材料的3D结构的分析，核电站中使用的蒸汽发生器材料中的裂纹，发光二极管的发展，复合材料材料的分析，分析地球上最古老的地质材料，月球样品，光子结构和超材料。迫切需要这些工具以实现材料的正确识别，即利用等离子体FIB的独特高通量铣削能力的3次材料重建。该工具还将对其样本进行更快的反馈，对结果的更可靠解释和研究进展更快，从而导致更相关和具有国际竞争性的出版物。除了拥有47个HQP的7个研究小组之外，他们在拟议的项目（及其HQP）中的18个合作者涉及研究和工业伙伴，该工具将位于加拿大电子显微镜（CCEM）（CCEM），这是一个真正的开放式设施，该设施由一项由用户组成的启用的主要科学启动支持，该工具是该工具的范围，该工具是该工具的，该工具是该工具。该中心每年支持430多名用户，他们在包括PFIB在内的设施中使用多种工具。他们还将使用此HT-EDS仪器进行工作。 CCEM设施与专门的技术人员一起运行所有仪器工具，他们培训用户的适当操作其操作的所有仪器，从而确保设备将被广泛有效地使用。
