Abstract: Two or more separate discharge spaces (8, 9) are provided in the discharge vessel (2) of a dielectric barrier discharge lamp (1), said discharge spaces (8, 9) each being filled with a discharge medium. This provides the possibility of producing radiation with two or more wavelengths which are characteristic of the respectively used discharge media using a single lamp (1).

Abstract: A dielectric barrier discharge lamp (1) with a discharge vessel, which has an outer tube (2), which surrounds a discharge space (4) filled with a discharge medium, an outer electrode (6), which is arranged on the outer side of the outer tube (2), an elongate inner electrode (7), which is arranged axially within the outer tube (2), at least one retaining disk (8) with an axial bore, through which the elongate inner electrode (7) runs, the retaining disk (8) extending substantially from the inner electrode (7) up to the inner side of the outer tube (2), as a result of which the inner electrode (7) is centered at least indirectly within the discharge vessel. The retaining disk (8) is supported on both sides loosely in the direction of the longitudinal axis by means of a supporting means (9a-9c) on the left-hand side and a supporting means (10a-10c) on the right-hand side.

Abstract: The invention relates to a dielectric barrier discharge lamp in a coaxial double-tube arrangement, comprising an exterior electrode (6), and interior electrode (7), and an auxiliary electrode (8). The interior electrode (7) is designed as an electrically conductive layer placed inside the interior tube (3) of the double-tube arrangement. The auxiliary electrode (8) is designed, for example, as a metal tube or pipe and is also disposed inside the interior tube (3), specifically in direct contact with the layer. In this manner, the conductivity of the interior electrode (S) is improved.

Abstract: A dielectric barrier discharge lamp (1) configured as a coaxial double tube comprises an inner tube (3), which is disposed coaxially inside an outer tube (2). The inner tube (3) comprises an inner electrode tube (8) provided for receiving the inner electrode (7) and a getter tube (10) provided for receiving getter material (9). The inner electrode tube (8) and getter tube (10) are separated from each other in a gastight manner by a partition (11).

Abstract: The invention relates to a method for treating, particularly cleaning, modifying, and/or activating surfaces, using UV/VUV irradiation of a UV/VUV lamp and additional gas discharge. A dielectric barrier discharge lamp (1) is preferably used as the UV/VUV lamp, comprising a planar window segment (7) for emitting the UV/VUV radiation. The lamp (1) extends into a process chamber (17). The additional gas discharge is generated in the region of the outer side of the window segment (7) of the lamp (1). The substrate to be treated is disposed within the process chamber (17), near the window segment (7).
