Cold Cathode Gas Diode | Applications of Glow Tubes

Cold-Cathode Gas Diode Fig. 3.6 shows the cut-away view of the cold-cathode gas diode. It essentially has two electrodes, anode, and cathode mounted fairly close to each other in an envelope filled with few inert gases at small pressure. The anode is in the shape of a thin wire whereas cathode is of the cylindrical … Read more
