Abstract:
A new electron-optical scheme of an axially symmetric mirror energy analyzer based on the electrostatic decapole-cylindrical field is presented. A trajectory analysis of electron motion is performed. Design features of the proposed energy analyzer scheme are described. Second-order focusing regimes for two configurations are numerically calculated: (1) a ring source and its image located in the region of the inner cylinder and (2) a point source located at a great distance from the energy analyzer on the symmetry axis. It is shown that on the basis of the decapole-cylindrical field, a long-focal-length mirror energy analyzer with “axis–ring” type focusing can be built. Instrumental functions for two regimes of the energy analyzer are given; energy resolution and luminosity of the device are estimated.
