    Abstract: This invention provides a cold-cathode gas-discharge tube comprising a gas-tight, electrical-insulating housing, a control cathode attached to and surrounding the outside of the gas-tight housing, two spaced main electrodes symmetrically mounted in the housing with their frontal surfaces facing each other, metallic rings attached to the frontal surfaces of both main electrodes, and layers of an activating material adhered to the frontal surfaces of both main electrodes within the metallic rings, whereby the main electrodes become in effect hollow electrodes.

    Abstract translation: 本发明提供一种冷阴极气体放电管,其包括气密电绝缘壳体,连接到气密壳体外部并围绕气密壳体的外部的控制阴极,两个间隔开的主电极对称地安装在壳体中,其正面 表面相互连接的金属环,两个主电极的正面连接的金属环,以及附着在金属环内的两个主电极的前表面的活化材料的层,由此主电极成为中空电极。
