Cathode ray storage tube having a target dielectric provided with collector electrode segments extending therethrough

A cathode ray storage tube provided with a storage target having a multiplicity of segments of the collector electrode extending through the dielectric layer of the storage target. These segments comprise glass beads secured together and to a surface of an insulating support plate, a conductive collector electrode coating is applied onto the support plate surface and glass bead segments and then the storage dielectric layer is applied thereover which has proper thickness so that the segments extend above the dielectric thereby providing collector areas for collecting secondary emitted electrons from the dielectric.
