Notes: A description is given of an electron microscope system equipped with computer controlled electronic counting and recording of microscope images and diffraction patterns. An electrostatic reverse-field energy filter lens provides energy discrimination, and a unique insulated digital-to-analog converter provides computer control of the bias voltage added to the high voltage on the lens. Examples of scans across diffraction rings and thickness fringes in Al wedges are given showing the intensity from only the elastic electrons and from those electrons which have lost energy due to plasmon excitation.

Notes: [Auszug] The types of discharge in which we have been interested are those which could provide a mechanism for the ignition of explosions in large oil tankers. Electrostatically charged mists can be generated in cargo holds by tank cleaning operations with high pressure water jets and by sloshing of water ...
