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.
