Abstract: The invention relates to a device for producing and/or confining a plasma, said device comprising a chamber in the space of which the plasma is produced and/or confined, said chamber including a wall defining a housing inside the chamber and encompassing said space, wherein said device is characterized in that it comprises at least one assembly for producing and/or confining plasma, each assembly being composed of magnets having only an axial magnetization direction and being recessed in the wall defining the housing, so that the magnetization direction of all the magnets defining each assembly is substantially perpendicular to the housing defined by the wall and so that the assembly is substantially symmetrical to the housing, wherein the magnetic field lines do not extend through the wall of the chamber. The invention also relates to a method for producing and/or confining a plasma.

Abstract: The invention concerns a device for producing and/or confining a plasma (10), comprising a recipient (13) within the volume of which the plasma is produced or confined, wherein said recipient comprises a wall (1) defining a lining (15) at the inside of the recipient and encompassing the volume, characterized in that it comprises at least one annular magnet (30), centered around a normal (14) with respect to the lining, having radial magnetization direction, such that the magnetization direction is significantly perpendicular to said normal to the lining. The invention also concerns a method for producing and/or confining a plasma.

Abstract: A device of a plasma (5) for confinement of a plasma within a housing (1), comprising creation means for creating a magnetic field, said means being a series of permanent magnets (3) for creation of a magnetic field presenting an alternating multi-polar magnetic structure to the plasma and the magnets (3) restrict the plasma to a large volume, the magnets begin distributed in a discontinuous around the volume end said magnets (3) arc discharge, a distance within the housing at a separation from the walls of the housing by means of support shafts (4). The changes above have been provided to improve the clarification of the claim language and claims have been amended to correct a typographical error. Since the changes are minor and are intended merely to improve the legibility of the claims, obtaining authorization from application was not viewed as necessary.
