Abstract:

Electron-optical properties of a family of field structures which are inherent for electron spectrography and developed on the base of Eulerian uniform fields with a symmetry plane have been studied in this paper. This potential set under question was constructed using the Donkin's potentials which were conic ones generalized. The various operating modes of spectrograph in the process of particles motion in the symmetry plane were investigated. Afterwards the potential structure defined in the plane was restored into space using the algorithm worked out by the authors. The prospects for electron spectrographs based on these potential structures were analyzed.
