<p>A plasma pumping cell and method for pumping ions from a first region containing a plasma to a second region when the plasma pumping cell is interposed between the first and second regions, the plasma pumping cell including: a partition member (4) positioned between the first and second regions, the partition member (4) having a through opening defining a conduit (22); a plurality of magnets (24) positioned relative to the conduit in a manner to provide lines of magnetic force that extend through the conduit; a source of free electrons in communication with the conduit; and an electric potential source (34) disposed relative to the conduit to create an electrostatic field which accelerates ions from the conduit (22) to the second region.</p> |
