ABSTRACT:
Device for isotope separation by ion cyclotron resonance (ICR). This device comprises a vertical enclosure (2), means (6) for producing a homogeneous, vertical magnetic field in said enclosure, a plasma source (8) for producing in the central part of the enclosure an ion plasma of the isotope to be separated, means (10) for producing in the enclosure an electric field perpendicular to the magnetic field and oscillating at the ion cyclotron frequency of the isotope to be separated, which is adjusted as a function of the mass of said isotope, collection means (12) for recovering a mixture which is enriched and a mixture which is depleted with said isotope. The plasma source comprises a container (14) containing the element (20), whose isotope is to be separated and means (18) for ionizing atoms of the element. Application to the separation of the isotopes of gadolinium.
