Abstract

Refinements introduced into an electronic cathode ray tube cannon, in particular for television image presentation, the cannon comprising a perforated control electrode, in the form of a cap or cap, in which a cathode having an emitting terminal face is supported by a plurality of thin-walled support members, a support cylinder, a circular cylindrical insulating body, and an annular metal body that is attached to the control electrode, characterized in that the aforementioned insulating body consists of a glassy material. ceramic of a composition, in% by weight, comprised within the following limits: BaO 60-65; B2O3 20-25; SiO2 12.5-17; ZnO 0 - 7.5.
