Abstract: An abrupt transition-shielding device for permitting electron passage therethrough while separating a strong electric field from a field-free region. The shield is constructed of an array of thin equipotential members arranged in a particular pattern, either parallel to each other and to the incident electron path, or a cylindrical array of members arranged radially. The spacing between the members is completely unobstructed along the electron flight path to prevent any scattering of electrons especially in the low energy range.
