Abstract

An elongated dielectric barrier discharge lamp with outer and inner electrodes has a tube that is arranged on the lamp stand end of the discharge vessel and that surrounds the lamp stand. The tube serves to receive a seal in order to install the lamp in a process chamber in a gastight manner. Power supply of the outer electrodes is separated from the power supply for the inner electrodes coming out of the lamp stand by means of the above-mentioned tube. This makes it possible to prevent effectively parasitic discharges between the power supplies which are applied at different potentials during operation also in process chambers under negative pressure.
