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.
