Method and Device for Generating an Electrical Discharge

摘要

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.

主权项

1. A device for generating an electrical discharge comprising:
at least a first and a second electrode in a chamber, wherein an electrical power supply is provided in order to operate the first electrode as a cathode and the second electrode as an anode, wherein the first electrode has a closed antechamber with a metal wall and a gas supply into the antechamber, and wherein a tube consisting of a material different from the material of the wall of the antechamber is provided in order to conduct gas from the antechamber into the chamber, wherein a front portion of the tube facing the chamber is embedded in the wall of the antechamber, and wherein a rear portion of the tube has an end freely projecting into the antechamber into which gas from the antechamber can enter.
