Title: Electromagnetic mass distiller

Abstract: A device for segregating high-mass particles in a multi-species plasma from lower-mass particles has a chamber surrounded by a hollow annular shaped enclosure which defines a central axis. In a radial direction outwardly from the axis, the chamber includes a light mass collection section that is in fluid communication, through an intermediate section, with a filter section. A magnetic field, B.sub.z, is oriented parallel to the central axis in the filter section, and the filter section has an outer wall which is at a distance slightly greater than a distance "a" from the central axis. An electric field is crossed with the magnetic field and is perpendicular to the central axis in the filter section. Further, there is zero potential on the outer wall of the filter section while there is a positive potential "V" on the inner wall of the filter section. At least if one plasma source injects a multi-species plasma into the filter section for interaction with the crossed magnetic and electric fields to eject high-mass particles into contact with the outer wall, while low-mass particles are prevented from doing so. High-mass particles are differentiated from low-mass particles by a predetermined value M.sub.c, where M.sub.c =ea.sup.2 (B.sub.z).sup.2 /8V.
