The Schottky electron emitter is a predominant electron-emitting source in today s electron beam equipment. This book comprehensively covers the Schottky emitter, dealing with its theoretical as well as practical aspects. The main questions that are addressed in this book are: what is the Schottky electron emitter? How does it work? And how do its properties affect the performance of electron beam equipment?

The focus is on the direct link between the operating conditions of the source and the properties of the beam at the target level. This coupling is made clear by...
