ABSTRACT:
The target of a television camera tube comprises photoconductive material in the form of a regularly interrupted structure so that both the photoconductive material and parts of the signal electrode are accessible to the electron beam. The potential difference between the signal electrode and the cathode is adjusted so that during scanning, the signal electrode accepts a proportion of the beam current dependent on the local potential of the photoconductor surface, and the photoconductor is stabilized only during fly-back. The camera tube thus has an adjustable inherent amplification without increased inertia.
