  • Method of separation of palladium isotopes in electromagnetic separator using a source of ions
    Patent number: 6806462
    Abstract: A method of electromagnetic separation of palladium isotopes places working substance of metal palladium in a gas-discharge chamber crucible with a source of ions. The working substance is heated to vapors, the vapors of the working substance ionized in the gas-discharge chamber under the action of electron emission from a hot cathode, and ionic beams formed by electrodes of an ion-optical system. The ionic beams separate isotopes in a magnetic field, entrapping the ions in receiving boxes, the temperature of the gas-discharge chamber being maintained within 1500-1700° C. The method is effectively used for separation of isotopes Pd-102, Pd-104, Pd-105, Pd-106, Pd-108 b Pd-110 with a high enrichment degree.

  • Process for separation of low natural concentration isotopes in an electromagnetic separator with ion source
    Patent number: 6559402
    Abstract: A process of separating low natural concentration protons in an electromagnetic separator having an ion source utilizes X-ray spectral analysis to distinguish areas of separated, increased-content of isotope enriched substance so as to treat them separately from areas of separated, low-content of isotope enriched substance. The overall process includes placing a working substance of a separated element in a crucible of the ion source, heating the working substance up to vapor forming, ionizing the vapors in a gas-discharge chamber of the source under action of hot cathode electron emission, shaping an ionic beam by electrodes of ion-optical system, separating and shaping the ionic beams of isotopes in a magnetic field, catching the ions in boxes of a receiver, identifying areas in the receiver boxes of increased content of isotope enriched substance using X-ray spectral analysis, withdrawing enriched substance initially from these identified areas, and further processing.
