Abstract: A novel gas tube assembly and a novel connector assembly using the novel gas tube assembly. The gas tube assembly includes an outer conductive electrode having a generally tubular construction, an inner conductive electrode also having a generally tubular construction, and a pair of insulating members. The outer and inner electrodes have first and second ends. The insulators are attached to the first and second ends of both the outer electrode and the inner electrode retaining the inner electrode inside and spaced away from the outer electrode. The first and second ends of the inner and outer electrodes are sealed by the respective insulator. A chamber is defined between an internal surface of the outer electrode, an external surface of the inner electrode, and corresponding surfaces of the insulators. The chamber defines a toroidal void within the gas tube assembly which retains an inert gas therein.
