Digital camera for transmission electron microscopy

该提案要求设备将升级过时的原始数字成像系统用于透射电子显微镜（TEM）。我们目前的相机分辨率仅略高于1000万像素，以今天的标准来看是非常低的分辨率。这台相机要么不适合，要么勉强适合捕捉病毒、噬菌体、鞭毛亚结构、超小型免疫金颗粒和纳米管的细节，这些都是我们小组的研究材料。新设备将提高标本调查和图像捕获的速度，并将大大提高研究生使用和培训的便利性。阿尔伯塔大学生物科学系的先进显微镜设备被该系成员以及地球与大气科学系、化学与材料科学系、农业、食品与营养科学系的教师和学生广泛使用。新相机将具有高分辨率（1100万像素）和几乎实时的测量速度。光纤耦合而不是透镜耦合将意味着几乎没有照明损失，因此标本不会被不必要的光束强度“烧毁”，特别是在测量期间。我们将能够在更短的时间内获得更高质量的图像。这将减少观察标本所花费的时间和相关的操作成本。

This proposal requests equipment that will upgrade an outdated original digital imaging system for transmission electron microscopy (TEM). The resolution of our current camera is only slightly higher than 1000 mega pixels, extremely low resolution by today's standards. This camera is either unsuitable or only marginally suitable for capturing fine details of viruses, bacteriophages, substructures of flagella, ultra-small immuno-gold particles and nano-tubes, the research material of our groups. The new equipment will improve speed of specimen survey and image capture 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 camera will have a high resolution (11 mega pixels) and still practically real time survey speed. Fiber-optic rather than lens coupling will mean next-to-no loss of illumination so that specimens are not 'burned' by unnecessary beam intensity, especially during surveying. We will be able to obtain better quality images in a shorter time.  This will reduce time spent on viewing specimens and associated operating costs.
