This requested grant will fund a new partnership between a research group in chemistry at the University of Victoria and Hitachi High Technologies Canada. The project involves the design of holder for sample characterization using a Hitachi scanning transmission electron holography microscope (STEHM). The STEHM system (Hitachi HF-3300V ) is hosted at the Center for Advanced Materials and Related Technologies (CAMTEC) at the University of Victoria. The proposed activities involve direct collaboration between a postdoctoral fellow, a CAMTEC research scientist and a Hitachi Engineer. The goal is to evaluate the requirements for the holder implementation and provide a design. The uniqueness of the holder is that it will allow the coupling of optical excitation simultaneous to STEEM imaging. The design will then require numerical calculations to define the best approach for optical integration and evaluation of mechanical parts and holder that will best couple to the holder space in the microscope. The final product of this six month research project will be a design recommendation for the implementation of the holder. This holder has the potential to become a new product in the Hitachi Canada line of electron microscopy accessories.

这项申请的赠款将资助一个新的合作伙伴关系， 维多利亚和日立高科技加拿大。本课题涉及样品保持器的设计 使用Hitachi扫描透射电子全息显微镜（STEHM）进行表征。的 STEHM系统（日立HF-3300 V）托管在先进材料和相关技术中心 （CAMTEC）在维多利亚大学。拟议的活动涉及以下机构之间的直接合作： 博士后研究员，CAMTEC研究科学家和日立工程师。目标是评估 保持器实现的要求，并提供设计。保持器的独特之处在于， 允许在STEEM成像的同时耦合光学激发。设计将需要 通过数值计算确定光学集成和机械部件评估的最佳方法 和将最佳地耦合到显微镜中的保持器空间的保持器。这六个月的最终成果 研究项目将为保持器的实施提供设计建议。该保持器具有 有潜力成为日立加拿大电子显微镜配件系列的新产品。
