Abstract

1411853 Image pick-up tubes RCA CORPORATION 8 Feb 1973 [11 Feb 1972] 6137/73 Heading H1D In an image intensifier camera tube having a charge storage screen impacted on an input face by a focused electron image accelerated from a photocathode with an energy greater than 1000 electron volts, and read on the other side by a scanning electron beam, the input face is provided with a continuous buffering layer of chromium, to absorb some of the energy of the incident electrons and thereby prevent the loss of grey scale due to target saturation, without incurring the non-uniformity associated with the use of aluminium for this purpose. As described, the target 26 is a silicon wafer, the chromium layer 36 being evaporated on its input face, and the output face being formed with an array of discrete P-N junctions 38, separated by a web of insulating material 40, and provided with degenerately doped silicon contact pads 42 which are scanned by the beam 30. The chromium layer is 52 to 65 nanometers thick, depending on the image accelerating voltage, or 7À5 to 20 nanometers thick of provided with a superimposed aluminium layer 80 to 110 nanometers thick. Reference is made also to the use of the chromium layer also on a target formed by a single junction. The incident optical image is transmitted by the fibre optics plate 16 to the curved photo-cathode 22, the electron trojectories from which cross over one another at the input opening of the anode cone 24.
