Abstract

A Green's function technique for the computation of electric potentials in electrostatic systems of arbitrary configuration, especially with cylindrical symmetry, is developed. The system may include open boundaries and dielectric media. The integral equation is numerically solved by iteration. Its convergence is very fast. Computer calculated field and potential values are of high accuracy (usually better than 10-4). Errors in electron optical data, derived from trajectory computation, were found to be within fabrication tolerances of experimental systems. The computerized method proved to be an excellent tool for the design of electron optical systems, as electron image intensifiers.
