Abstract
The disclosure depicts in a television cathode ray tube having a getter containing a vaporizable, electrically conductive, gas adsorptive getter material, an improvement comprising an electrically resistive element for arc suppression, an electrically resistive element for arc suppression, internal voltage division, static elimination, RC signal coupling or the like. The resistive element is composed of a high resistivity material compatible with a clean, high-vacuum environment. The element is so widely and deeply cavitated and contorted at and below its nominal surface that the real surface of the element is shadowed and very greatly extended in area relative to the nominal surface of the element. The effect of this is that when the getter is flashed, the coating of conductive getter material deposited on the element is effectively dispersed and fragmented into isolated conductive islands. The result is to render tolerably insignificant the tendency of arc currents to travel over the surface of the element and thereby by-pass the body of the element.
