Abstract

The modern analytical transmission electron microscope gives signals from both elastically and inellastically scattered electrons at rates up to a few magabytes per second. A flexible multiasking system is needed to effectively integrate the information from a microscope with multiple detectors while synchronously controlling selected optical parameters of the instrument. We describe a system based on a Digital Equipment LSI-11 microcomputer equipped with a frame buffer and show how it has been used to develop new experimental capabilities such as time-resolved spectroscopy and multi-spectroscopy elemental mapping.
