Abstract
A device for treating with microwave plasma a container. The container is placed in a chamber (12) made of a conductive material and is rotationally symmetrical, and the device includes a wave guide tunnel (15) substantially perpendicular to the axis (A1) of the chamber and which emerges therein in the form of a rectangular window whereof the smaller dimension corresponds to its dimension along the chamber axis. The internal diameter of the chamber (12) is such that the microwaves are propagated in the chamber mainly according to a mode whereby the electric field resulting from the propagation of the microwaves exhibit an axial rotational symmetry.
