摘要： The invention relates to a device for confinement of a plasma (5) within a housing (1), comprising 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. The invention is characterised in that the magnets (3) restrict the plasma to a large volume, the magnets begin distributed in a discontinuous manner around the volume and said magnets (3) are arranged within the housing at a separation from the walls of the housing by means of support shafts (4).
