Title: Superorthicon-type television camera tube having target and fine-mesh metal grid coated with semiconductor material of relatively low inelastic electron reflection factor

Abstract: A superorthicon-type television camera tube with a photoelectric cathode, a target spaced opposite the cathode and including a film and a fine mesh grid arranged between the film and the cathode. A coating is provided on both the grid and the film and is constituted of a semiconductor material having an inelastic electron reflection factor lower than that of the material of the target. The coating of semiconductor material is on the film and on the grid on the side facing the cathode.
