The structure of a multipolar magnetic confinement and passive electrostatic for the production of dense plasmas, homogeneous and low temperature electronique

摘要

Production of plasmas. The structure according to the invention is characterised in that it consists of a multipolar cage comprising an armature 18 made of non-magnetic material, in the form of a casing and supporting bars 20 of a permanent magnetic nature, extending parallel to one another whilst presenting, directed along the volume defined by the cage, a face of successively differing polarity, and in that this cage includes means 21 of passive electrostatic confinement comprising layers of insulating material extending in front of those faces of the bars directed towards the inside of the cage. Application to the production of dense, homogeneous plasmas of low electron temperature. IMAGE
