This proposal requests funding to replace our aging and failing scanning electron microscope (SEM) that has been used heavily for 17 years but can no longer be serviced. SEM technology has advanced significantly over the last two decades. The new SEM will double the speed of specimen survey and image acquisition, enhance resolution of images even at low vacuum and beam power (accelerating voltage), and provide exceptional resolution images at high vacuum even for low accelerating voltages. The new equipment will support the research of many academic staff, and will vastly improve ease of use and training by our graduate students. The Advanced Microscopy Facility in the Department of Biological Sciences at the University of Alberta is intensively used by members of this department as well as by faculty and students from the Departments of Earth and Atmospheric Sciences, Chemistry and Materials Science, and from Agriculture, Food and Nutritional Sciences. The proposed new microscope will have high resolution (up to 3nm at 30Kv) and a fast scan rate (10-21 frames/s). Three axis joystick motorized navigation plus two tilt directions will allow students to obtain publication-quality images quickly. This instrument is urgently needed for all our groups to continue their research.

该提案要求资金替代我们的老化和失败的扫描电子显微镜（SEM），该电子显微镜已被大量使用了17年，但不能再维修。在过去的二十年中，SEM技术已经取得了显着发展。新的SEM将使样品调查和图像采集的速度增加一倍，即使在低真空和梁功率（加速电压）下，也可以增强图像的分辨率，并在高加速电压下甚至在高真空中提供出色的分辨率图像。新设备将支持许多学术人员的研究，并将大大提高研究生的使用和培训。艾伯塔大学生物科学系的先进显微镜设施由该系成员以及地球和大气科学系，化学和材料科学的教职员工以及农业，食品和营养科学的教职员工以及来自地球和大气科学系的学生深入使用。提出的新显微镜将具有高分辨率（30kV时3nm）和快速扫描速率（10-21帧/s）。三个轴操纵杆机动导航以及两个倾斜指示将使学生能够快速获得出版物质量的图像。我们所有小组都需要迫切需要该工具继续他们的研究。
