Formation of an electron beam by an electron-optical system using a composite field emitter made of thermally expanded graphite and a mixture of thermally expanded graphite with diamond granules

Formation of an electron beam by an electron-optical system using a composite field emitter made of thermally expanded graphite and a mixture of thermally expanded graphite with diamond granules

In the paper, the characteristics of electron flows formed by an electron-optical system with composite field emitters, made from thermally expanded graphite or a mixture of such graphite with diamond granules have been studied. These cathodes were developed at the Saint Petersburg Polytechnic Unive...
