Abstract
Discusses the singularities and approximations that occur in the charge-density method of solving electrostatic problems in which space-charge is absent (Laplace's equation) or present (Poisson's equation). Describes the application of the method to electrostatic lenses in general and to the particular case of a high-current triode gun.Keywords
