METHOD AND DEVICE FOR GENERATING PLASMA THROUGH ELECTRIC DISCHARGE IN DISCHARGE SPACE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for generating a plasma through electric discharge which result in a substantially longer operational life or to a higher average loading capacity of two electrodes with the use of technically simple means.

SOLUTION: In the method and the device for generating the plasma through electric discharge in a discharge space including at least two electrodes, at least one of the electrodes is formed from a matrix material or a carrier material so as to make an erosion-susceptible range with an evaporation spot formed by at least current flow. In the method and the device, a sacrifice material 38 wherein a boiling point of the sacrifice material 38 during a discharge operation is lower than a melting point of the carrier material 30 is arranged on at least the evaporation spot so as to mainly create a charge carrier generated in the current flow from the sacrifice material 38.
