    摘要: A device to generate excited and/or ionized particles in plasma with a generator to generate an electromagnetic wave and at least one plasma zone, in which the excited and/or ionized particles are formed by the electromagnetic wave. The plasma zone is formed in an interior chamber of a conductor for the electromagnetic wave.

    摘要: A plasma discharge tube (5) having a diameter that corresponds to a quarter wavelength of the standing wave is selected and the waveguide system (2) is dimensioned and tuned such that the standing wave forms a first voltage maximum at a first side of the plasma discharge tube (5) and the standing wave is also supplied reflected, so that it forms a second, anti-phase voltage maximum at a second side of the plasma discharge tube (5) that lies opposite the first side and faces toward an end termination (12) of the waveguide system (2). A controlled magnetic field is applied in order to achieve an especially low working pressure.
