IMPROVEMENTS IN ELECTRIC OVERVOLTAGE DISCHARGE DEVICE
The device contains an envelope which includes an elongated hollow insulator bonded to the rim of a bottle-like metallic member. An elongated metal electrode support member extends concentrically through the hollow insulator and is spaced from the bottom of the bottle-like member to form a gap. The bottom of the bottle-like member is indented in the center to form an electrode. The gap is the greatest region of field concentration between the opposing metal surfaces. An inert ionizable medium is within the envelope at a pressure of 0.01 to 2500 mm of Hg, and radioactive means (nickel-63 and krypton-85) are contained in the envelope for maintaining ionization at a predetermined level lower than the normal level of ionization upon discharge of the gap.
