ABSTRACT:
An improved radiation-emitting device of the type for containing a gas and 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-demension. The first principal member is radiation-transmissive and the second is preferably radiation-reflective, having a metallic inner coating. Plural electrodes are preferably used. The second principal member is preferably inwardly-concave. One preferred embodiment has a first principal member which is outwardly concave and preferably has a high gas pressure. Another has an outwardly convex first principal member. Another has concentric inner and outer tubes as radiation-transmissive and radiation-reflective members, respectively, the inner tube serving as a flow path for a liquid to be treated.
