Abstract

In an excimer radiator, especially an UV radiator with dielectrically impeded discharge, a first electrode is applied in a discharge chamber sealed from the ambient atmosphere onto an elongated support which, as seen in a radial direction from its longitudinal axis, is surrounded by a discharge vessel of quartz defining the discharge chamber; on the outside of the discharge vessel a second electrode is disposed which is permeable to at least a portion of the radiation produced in the discharge chamber. In order to maintain sufficient stability in the incandescent processes necessary in the manufacture of the radiator in spite of the elongated internal electrode, one end of the support (8) of the first electrode is placed and affixed in a hollow body-like section (5) tapering as seen in longitudinal section, while the other end of the support (8) is connected to a base (11) which has at least one current lead-through (16) for the first electrode (9).
