Abstract
Apparatus for the formation of excited or unstable gaseous molecules, comprising a tubular gas passage (5) having an axis, formed between a first electrode (1) and a dielectric tube (3) coaxial to the first electrode and supporting a second electrode (4), the electrodes being connected to a high voltage high frequency source (13). The first electrode (1) surrounds the dielectric tube (3) and comprises an elongated gas inlet (7) and outlet (8) parallel to the axis and diametrically opposed to each other on opposite sides of the dielectric tube (3). The second electrode (4) is a layer of metal applied to the internal wall of the dielectric tube (3). The second electrode (4)is formed by metallization of the internal wall of the dielectric tube (3). The gas inlet (7) and outlet (8) have a height not exceeding the radial thickness (e) of the gas passage (5). The external wall of the dielectric tube is covered with a thin layer (21) of enamel. A refrigerant such as Freon circulates within the dielectric tube (3) and the second electrode (4). Used for the production of ozone, to supply a mixed CO.sub.2 laser, or for the production of atmospheres for nitriding metal, or for the production of reducing atmospheres.
