Abstract
A device and method for generating an electrical discharge are described. A first electrode (30) is operated to be a cathode relative to a second electrode (16). A gas is introduced into the chamber (14) by the first electrode (30). The first electrode (30) has a closed antechamber (32) with a metal wall (34). A tube (36) consisting of a different material than the wall (34) is provided through which the gas from the antechamber (32) is conducted into the chamber (14). A front portion of the tube (36) is embedded in the wall (34) of the antechamber (32). In its rear portion, the tube (36) has a free end projecting into the antechamber (32). A stable electrical discharge can be generated thereby in a particularly easy manner.
