ABSTRACT:
Electric discharge tube having a hollow cylindrical bulb formed either of a ceramic material or from sapphire having first and second open ends. First and second end caps or closure members are fitted over the ends to form capillary action passages between the first and second closure members and the end portion of the bulb member such that solder will flow when heated to join the members together on cooling of the solder. One or more of the end closure members may have a metallized surface formed thereon. The end closure members may extend along either the inside or the outside surface of the cylindrical bulb member or both the inside and the outside surfaces of the bulb member. A hollow cylindrical ceramic member may be fitted to the end portion of the bulb member and itself be fitted with a plurality of closure members at one of its ends and a third hollow ceramic member at its other end to form an air-tight sealed tube.
