Acquisition of a Field Emission Scanning Electron Microscope with a Cryostage System and an X-ray Microanalyzer.

康奈尔大学需要一台配备冷冻转移/状态系统和x射线显微分析仪的高分辨率场发射扫描电子显微镜。该仪器将广泛用于农业、生物学和相关科学的项目，并将位于布拉德菲尔德霍尔电子显微镜设施，由首席研究员负责，他也是该设施的主任。已有15年历史的传统扫描电子显微镜AMRAY 1000目前在设施中，无法满足拟议项目使用所需的规格。虽然该仪器是拟议项目所必需的，但它也应该有利于校园内可能需要高分辨率生物标本扫描电镜成像或检查冻水标本的能力的其他研究项目。目前在布拉德菲尔德霍尔设施进行的培训/教学计划应该使最先进的设备随时可供广泛的研究人员使用，包括教职员工、博士后助理、研究生、本科生和技术人员。

A high resolution field emission scanning electron microscope equipped with a cryotransfer/state system and a x- ray microanalyzer is needed for investigators in biological and related sciences at Cornell University. The instrumentation will be used in a wide range of projects in agriculture, biology and related sciences, and will be located in the Bradfield Hall Electron Microscopy facility under the responsibility of the Principal Investigator who is also the director of the facility. The 15 year old conventional scanning electron microscope AMRAY 1000, currently in the facility, cannot meet the specifications needed for use in the proposed projects. While the instrumentation is necessary for the proposed projects, it should also benefit other research projects in the campus that may need high resolution SEM imaging of biological specimens or the capability to examine frozen-hydrated specimens. The training/teaching program that is currently i n place at the Bradfield Hall facility should make the state-of-the-art equipment readily available to a wide body of researchers including the faculty members, postdoctoral associates, graduate students, undergraduates and technicians.
