Abstract

Monochromators require feed beams with defined aperture angles and a low energy spread. After presenting some basic concepts of thermionic emission we describe the technical aspects of trajectory calculations in the presence of space charge. Emission systems with differently shaped lenses are studied and their performances are compared.
