Abstract

An electron beam or similar charged particles may be deflected by passing through an electrostatic field produced in a deflecting structure. The degree of deflection is controlled by rotating the deflecting structure and path relative to one another. The beam may be rotated relative to the structure by a magnetic beam deflector which compensates for a range of electron energies within the beam so that all electrons are deflected in the electrostatic field by an equal amount.
