Abstract
A target structure for electronic storage tubes which is of the 'coplanar grid' type. The target comprises a conducting layer which in a preferred configuration has slender elongated pedestals supporting elongated spaced parallel insulating strips which serve as the coplanar grid. The spaces between adjacent edges of insulating strips expose regions of the conducting layer to enable an electron beam to contact the exposed regions of the conducting layer. The pedestals support the insulating strips a spaced distance above the exposed regions of the conducting layer to form 'vacuum gaps' which serve to inhibit electrical charge on the surfaces of the insulating strips from transferring to the interface between each strip and the vacuum gap. The pedestals may be an integral part of the conducting layer or may be formed from an insulating material. Methods for producing the novel target are described.
