ABSTRACT:
A digitizing matrix for electron beams of the type wherein electrons are permitted to pass through openings in the matrix to a target which is scanned with an electron beam. The target is formed from a series of stacked electrode units each formed by electrically-conductive layers extending perpendicular to each other and through which the aforesaid openings pass. By establishing an electrical potential between crossed conductive layers, an electric field will be generated in the area defined by the crossed conductors to stop passage of electrons through one or more of the openings in the aforesaid area. The invention is characterized in that the stacked electrodes are formed as a single unit by thick film techniques wherein successive layers of a dielectric and crossed conductive layers are formed. The assembly facilitates the fabrication of very thin, high electron efficiency, low capacity and low cost flat panel matrices.
