Transmission properties of a cylindrical mirror analyzer viewed in energy-angle space

Abstract

In this paper we present a general method for calculating the transfer and transmission functions of a cylindrical mirror analyzer (CMA) which employs the exact, albeit numerical, solutions of the particle equations of motion. The analysis incorporates emission from extended sources and easily lends itself for use with elements which preretard the particle’s kinetic energy. Our approach leads directly to a convenient display of the analyzer transmission in energy‐angle space which provides a vantage point for assessing the role of each CMA aperture in the transmission process and for assessing the influence of the angular distribution of the emitted particles on the energy transfer function. The general method can be extended to include any dispersive analyzer for which the particle equations of motion are solvable.
