Re-generable Field Emission Cathodes Part I : Surface Morphology of Emitter Apex

Abstract

This is the first part of a two-part paper that focuses on a field-emission cathode for use in Electric Propulsion (EP) that has the potential for very long lifetime due to its ability to be re-generated when the emitter tip become damaged. The field-emitting tips were formed by the application of an ion-extracting electric potential applied to a heated… (More)
