Abstract
We report on the design and measurements of a new direct electron imaging sensor. The active pixel sensor array consists of 512 by 550 pixels, each 5 by 5 μm in size, with a ∼8 μm epitaxial layer, to achieve an effective fill factor of 100%. Spatial resolution of 2.3 μm for a single incident e-has been measured. Tests have been performed with 200 and 300 keV beams, and an image of a catalase crystal, taken with the sensor, is presented. This novel sensor technology opens the door for studies of nanostructures and biological samples at higher resolution in both space and time.
