摘要： The invention relates to a device for producing and/or confining a plasma (10), said device comprising a chamber (13) in the space of which the plasma is produced and/or confined, said chamber (13) including a wall (1) defining a housing (15) inside the chamber (15) and encompassing said space, wherein said device is characterised in that it comprises at least one assembly (30) for producing and/or confining plasma, each assembly (30) being composed of magnets (3) having only an axial magnetisation direction and being recessed in the wall (1) defining the housing, so that the magnetisation direction of all the magnets (3) defining each assembly (30) is substantially perpendicular to the housing (15) defined by the wall (1) and so that the assembly (30) is substantially symmetrical to the housing, wherein the magnetic field lines (5) do not extend through the wall (1) of the chamber. The invention also relates to a method for producing and/or confining a plasma.

摘要： 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.
