Abstract
The hyperfrequency energy is conveyed through a waveguide (1) having a rectangular section. A central plasmagenic gas and an annular sheathing gas are supplied through a T-shaped transverse pipe (2). The upper branches of the T extend in a sealed manner through the small sides of the waveguide. The stem of the T extends with clearance through an opening (7) formed in a large side of the waveguide and is provided with a nozzle (22) which is surrounded by a sleeve (3) terminating in a rolled-over flange (25). Application in the treatment of surfaces and the production of chemical reactions.
