Abstract

931,384. Discharge tubes. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE FIL. Dec. 13, 1961 [Dec. 21, 1960], No. 44595/61. Class 39 (1). A photo-cathode structure 1, e.g. for use in a cathode-ray tube 11, itself comprises a gaseous discharge tube, the gaseous discharge exciting either directly or through a fluorescent coating applied to the inner wall of the container, the photo-emissive coating 8 provided on the front surface of an, e.g. glass, window 3. The photo-emissive coating is deposited on a thin transparent conductive film. The gaseous discharge, which may be pulsed, is set up between the wall of the container and a metal rod electrode 5 traversing a glass or ceramic wall 4. The gas filling may be argon, neon or hydrogen at 10<SP>-3</SP> mm. Hg.
