Abstract
A low-pressure discharge lamp, in particular a deuterium lamp, including a cylindrically symmetric partition unit which forms two hollow spaces at each of the sides of the discharge lamp. Both hollow spaces are connected through an opening in the partition unit, which confines the plasma generated by a high-frequency electromagnetic field to pass through the opening to increase the intensity of the emitted radiation. Both sides of the cylindrically symmetric partition unit are provided with a hermetic seal, at least one of which sides is a radiation emission window. The generation of the electromagnetic field takes place capacitatively through electrodes located on the sides of the discharge lamp. At least one of the electrodes is disposed on the radiation emission exit window and has an opening for the radiation to exit.
