摘要
The invention includes a method for obtaining an exact electrostatic quadrupole field by the use of simple structures having high resistance materials of uniform or continuously varied thickness to form closed boundaries. The potential of these boundaries is continuously varied with respect to position in accordance with specified design criteria. The method and structures can be used in electron optical systems and related scientific instruments.
