Abstract
This invention provides methods and apparatus for ionizing all the elements in a complex substance such as radioactive waste and for separation of some of the elements from the other elements. One principal methods utilizes plasma confinement by toroidal magnetic fields as a gate to regulate when and where specific elements are collected. While the plasma is confined, some of the species are removed by repeatedly cycling all of the species between the plasma and the deposition stages lining the walls, whereby some species preferentially accumulate on the deposition stages. The other species are then diverted into an additional containment vessel for collection or additional separations. The apparatus is a large volume plasma processor with multiple containment vessels. The invention provides for the characterization of waste material, and for its separation all within one serf contained vacuum environment. Other applications include remediation of chemical toxic wastes and chemical and germ warfare weapons.
