Abstract: A GAUZE ELECTRODE FOR VIDICON ("PLUMBICON") HAVING A DIAMETER OF 15 MM. OR SMALLER. A MAXIMUM LIGHT TRANSMISSION OF THE GAUZE ELECTRODE IS OBTAINED BY FIRST ETCHING COPPER GAUZE WHICH IS MANUFACTURED BY ELECTRODEPOSITION TO A LIGHT TRANSMISSION OF 70% AND THEN SECURING IS BY DIFFUSION AT APPROXIMATELY 2/3 OF THE MELTING TEMPERATURE OF THE MATERIAL OF THE GAUZE BETWEEN TWO COPPER-NICKEL RINGS. THE WIDTH OF THE RINGS IS SMALLER THAN 15% OF THEIR ORIGINAL OUTSIDE DIMENSION.
