- Аннотация: This monograph is dedicated to the basic methods of the design of electrostatic energy analyzers that are widely used in electron spectroscopy. Of the variety of requirements that are commonly imposed on the geometrical structure and output characteristics of energy analyzers, two are of principal importance. These are the order of angular focusing and energy dispersion, which define the sensitivity and resolution power of a particular energy analyzer, respectively. We consider three different and mutually complementing approaches aimed at the evaluation of the focusing and dispersion properties of energy analyzers. The first of these approaches—the analytical approach—is applicable in the case when the electrostatic fields and electron trajectories can be represented in the form of explicit analytical expressions. Not infrequently, the fields and trajectories may be obtained as integrals or asymptotically convergent series; this comprises the second, approximate-analytical approach elucidated in the monograph. In more general and sophisticated cases, the might of the modern numerical methods of computational mathematics should be used, which represents the third approach considered here. This book can be useful for students of charged particle optics; scientists and engineers involved in the development of the new, advanced energy analyzers; and users of electron spectroscopy devices who want to keep abreast of current trends in this area.
