Apparatus and method for generating a plasma beam

The invention relates to a device for generating a plasma beam, comprising a housing (2) and having at least two electrodes (4), wherein the housing (2) having a gas inlet (6) and a gas outlet (8). The invention is based on the technical problem of specifying an apparatus for producing a plasma beam, comprising in particular a space-saving flow cross-section for the working gas in the interior of the housing (2) and thus also small external dimensions. is solved the technical problem in that the at least two electrodes (4) are integrated in the side wall of the housing (2).
