Simulation of space charge fields in unbounded geometries

The authors present a numerical technique based on the combined method of charge simulation and the method of characteristics to evaluate fields in unbounded geometries. The numerical procedure utilizes a nonrigid grid structure which, after convergence to a self-consistent solution, is a map of the field lines and equipotential contours. The numerical procedure is applied to a rod-to-plane geometry, and the simulation predictions are compared with experimental data.<
