ABSTRACT:
A technique to produce a device for generating an electric field is disclosed. This electric field may be customized to direct movement of charged particles in a predetermined manner. Moreover, this device is readily installed and removed from a charged particle analyzer to facilitate interchange with other devices capable of generating electric fields with different characteristics. The device may be provided by etching an electrically conductive layer clad to a flexible dielectric substrate to define a predetermined conductive pattern. This pattern is then oriented relative to a charged particle pathway and an electric potential applied to generate the desired electric field.
