ABSTRACT:
An improved radiation-emitting device of the type for containing gas and an electron flow therein between electrodes. First and second separate elongated principal members form an elongated envelope volume having constant cross-sections along its length. The members are arranged and configured so that the envelope volume is less than that of a cylinder of similar cross-dimension. The inner surface of the second principal member has projecting structures which extend to distal ends adjacent to the first principal member.
