Abstract
A charge storage target of cathode ray electron devices comprises a conductive layer and a resistive layer having a common interface therewith, and an insulative layer. At least one of the layers has perforations so that only the resistive and insulative layers are exposed to electron impingement. The perforations define a plurality of elemental regions on which elemental electron image is stored. The resistive regions that cover the underlying conductive layer serve as buffer areas for the entering electrons of which the magnitude is proportional to the amount of charges deposited on the exposed insulative regions, and transfer the stored energy to the underlying layer.
