    Abstract: A picture tube designed for providing an electrical output includes a vacuum enclosure provided with a window transparent to the radiation to be converted to an electrical signal and a window transparent to a scanning light beam. The enclosure houses an assembly including a screen and a photocathode having a mosaic of picture storage elements, and an electron-emissive cathode for establishing a reference potential on the photocathode, an anode for collecting signal electrons, a field grid and electron optics. An external light source is used to provide a light beam for scanning the photocathode.

    Abstract: In a radiation detector two photocathodes are provided one on either side of a channel amplifier plate. One of these photocathodes is provided, so as to be electrically floating, on a layer of a dielectric on the opposite surface of which an electrode is provided, the lateral conductivity of this photocathode being low either owing to its subdivision into electrically isolated areas or owing to the choice of material.The potential distribution in the detector can be reversed from a write-in situation to a read-out situation so that the channel plate can be used twice and the amplification is subdivided, enabling it to be increased to a higher level.
