Modeling of electrostatic decapole-cylindrical mirror analyzer

Abstract

Numerical modeling of electron-optical scheme of electrostatic decapole-cylindrical mirror energy analyzer has been carried out. Trajectory analysis of the charged particles motion in decapole-cylindrical field has been conducted. Two regimes of second-order angular focusing (“ring-ring” and “axis-ring” types) were found. Focusing properties of decapolecylindrical analyzer in second-order angular focusing regime for different types of focusing were calculated. Instrument functions were obtained; energy resolution and luminosity of device were estimated.
