Use of a Platinum Filament in the Electron Microscope

Francis W. Bishop

Open publisher page 2 citations

Abstract

A platinum filament covered with a mixture of oxides has been used to replace the tungsten filament in the RCA model EMU-2 electron microscope. This unit originally was used on an Akashi electron microscope. Since the filament operates at a low temperature, evaporation of the filament itself is very slow. The electron source is very small. The drift of illumination is small and the field of illumination is quite uniform.
