Title: Studying of Explosive Electron Emission From “Whisker” Cathode Using X-Ray Point-Projection Radiography

Abstract

The results of direct observation of the initial phase of explosive electron emission using high-resolution X-ray radiography in X-pinch radiation are reported here. The confirmation of common “Ecton” theory was not found within achieved temporal and spatial resolutions. A mechanism involving the surface breakdown of whiskers that leads to plasma development is proposed.
