The electron-optical scheme of the axially-symmetric electrostatic mirror-type energy analyzer of charged particles beam based on a multipole electrode system is proposed. The field of the energy analyzer is designed as a superposition of the base cylindrical field and set of circular octupole coaxial with base field. The trajectory analysis of the electron-optical system was carried out by a numerical method. Corpuscular-optical parameters of system are calculated. The “ring-ring” type third-or
