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.

这项提案要求提供资金，以更换我们老化和故障的扫描电子显微镜(SEM)，该显微镜已大量使用17年，但已无法再维修。在过去的二十年里，扫描电子显微镜技术有了很大的进步。新的扫描电子显微镜将使标本测量和图像采集的速度提高一倍，即使在低真空和束流功率(加速电压)的情况下也能提高图像的分辨率，即使在低加速电压的情况下也能在高真空下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，并将极大地改善我们研究生的易用性和培训。阿尔伯塔大学生物科学系的高级显微镜设备被该系的成员以及来自地球和大气科学系、化学和材料科学系以及农业、食品和营养科学系的教职员工和学生广泛使用。建议的新显微镜将具有高分辨率(在30KV时高达3 nm)和快速扫描速度(10-21帧/S)。三轴操纵杆机动导航加上两个倾斜方向将使学生能够快速获得出版物质量的图像。我们所有的小组都迫切需要这个仪器来继续他们的研究。
