Abstract

1440139 Particle separators JERSEY NUCLEAR-AVCO ISOTOPES Inc 24 Oct 1973 [2 Feb 1973] 49415/73 Heading H1D In a method of separating isotopes using selective photo-ionization, a flowing plasma containing ions of the desired isotopes is given energy to raise the electrons to an energy level higher than the thermal energy level of the plasma thereby causing expansion of the electrons and the desired isotope ions which are thus deflected from the general flow direction and can be collected. In Fig. 3, uranium 72 is vaporized by an electron beam and is irradiated by laser radiation to produce isotopically selective electron transitions in a manner known per se. The resulting plasma is formed into a beam 88 and in the region of collector plates 92 is given the additional energy referred to above with a resultant expansion of the desired ions in a transverse direction causing the isotope to collect at 96, the other components of the plasma passing to a plate 100. The additional energy can be from a laser, an electric field between alternate plates 92, an oscillating magnetic field high frequency radiation, e.g. microwaves or electrons.
