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.
