Abstract
Axisymmetric and nonaxisymmetric electron space-charge lenses and sphe rical aberration correctors are studied theoretically. Many interestin g features of the space-charge devices are revealed by considering som e simple, but physically reasonable models. It is shown that a number of simple space-charge distributions can compensate for a large range of positive spherical aberrations. Several numerical examples are pres ented in some detail.
