CPO : Charged Particle Optics
http://www.electronoptics.com/
The CPO (Charged Particle Optics) program is a tool for analysing the static electric fields created by a number of electrodes. The software uses elements to simplify the electrode's shapes in order to plot the electrostatic potential. It can simulate the flight path of charged particles (such as electrons) within a two dimensional (2D) or three dimensional (3D) model of an electrostatic system. Magnetic fields can also be simulated. The software is commercial, however, a version is made available for students to use free of charge.
