Abstract
A camera tube system having an electron gun of the diode type. The electron gun is provided with an anode consisting of several parts. These parts are provided with apertures, are electrically separated and are adapted to be connected to means to control the potential. As a result of this, it is possible to generate a much larger beam current during the line flyback. This larger beam current makes it possible to avoid the so-called comet-tail effect.
