ABSTRACT:
A device having a camera tube of the vidicon type. During flybacks of the deflection, the beam current and the cathode potential is increased so as to achieve the so-called anti-comet tail effect. In order to ensure that the beam lands on the radiation sensitive layer perpendicularly everywhere during flybacks, as well as during scanning of the target, the electron beam is focused at the deflection point of the deflection coils during the flyback.
