We demonstrate the feasibility of a new type of electrostatic cylindrical analyzer terminated with plates with focus at 90degrees also in the presence of significant space charge. The transmission function is determined by numerical simulation of the trajectories after a full three-dimensional solution of the Poisson problem with boundary condition by an iterative finite difference algorithm. This device may allow a new generation of spin polarized electron energy loss spectroscopy experiments.

Abstract
We demonstrate the feasibility of a new type of electrostatic cylindrical analyzer terminated with plates with focus at 90degrees also in the presence of significant space charge. The transmission function is determined by numerical simulation of the trajectories after a full three-dimensional solution of the Poisson problem with boundary condition by an iterative finite difference algorithm. This device may allow a new generation of spin polarized electron energy loss spectroscopy experiments.
