NUMERICAL SIMULATION OF ELECTRON TRAJECTORIES FOR EELS

NUMERICAL SIMULATION OF ELECTRON TRAJECTORIES FOR EELS Electron energy loss spectrometers EELS for surface studies require a high energy resolution E 3 meV monochromatic electron beam with the highest possible current. In order to improve the transmission of such a device, and so the achievable current, a 3D simulation of electron trajectories taking into account space charge effects was performed for typical three lenses cathode systems, electrostatic cylindrical deflector analyzer CDA 127 and acceleration lenses. The results of the analysis are presented and their effects on the overall design of the device are discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering Emerald Publishing

Abstract

Electron energy loss spectrometers EELS for surface studies require a high energy resolution E 3 meV monochromatic electron beam with the highest possible current. In order to improve the transmission of such a device, and so the achievable current, a 3D simulation of electron trajectories taking into account space charge effects was performed for typical three lenses cathode systems, electrostatic cylindrical deflector analyzer CDA 127 and acceleration lenses. The results of the analysis are presented and their effects on the overall design of the device are discussed.
