A synthetic plasma source
Abstract
A synthetic plasma source producing a plasma beam with low temperature (0.3 to 0.5 eV, in the central column, but 3 to 5 eV with a tail of energetic electrons at r = 33 mm) and nearly maxwellian electron distribution is described. Two thermionic cathodes are used, one supplying energetic electrons that ionize the gas, the other, a lanthanum hexaboride plate in contact with the plasma, supplying thermal electrons.
