Interference Experiments with a Field Emission Electron Miscroscope

Open publisher page 2 citations

Abstract

We have modified a Hitachi HU 12 electron microscope by replacing the thermionic electron gun with a field emission gun. The design principles of this gun are substantially the same as those used in the scanning microscopes developed at the University of Chicago by A. V. Crewe and his collaborators. To accommodate the field emission gun in the conventional column two differentially pumped stages were employed, assuring a vacuum of better than 2 x 10−10Torr in the tip region.
