DEVICE FOR WEIGHT SEPARATION OF CHARGED PARTICLES Russian patent published in 2002 - IPC

FIELD: nuclear engineering. SUBSTANCE: device has vacuum chamber 1 accommodating coaxially arranged charged particle circular source 2, charged particle receivers 9 and 10, and separator 6. Charged particle source 1 consists of ionization chamber 3 and electrodes 4 forming a drawing electric field. Charge particle separator 6 is made in the form of single-band hyperboloid 7 and funnel 8. Hyperboloid 8 is bent by curves of orbits of light charged particles, and funnel 8 is bent by curves of orbits of heavy charged particles. Funnel 8 is installed inside hyperboloid 7 with combination in wide parts and reduction of cross-section of funnel 8 from region of combination to opposite end. Hyperboloid 7 and funnel 8 have longitudinal slots 11 located in separator symmetry plane. Charged particle source 2 is located at slots 11 near region of combination of hyperboloid 7 and funnel 8. Hyperboloid 7 and funnel 8 are made to pass direct currents. Invention is applicable in separation of isotopes from their natural mixtures. EFFECT: higher selectivity of charged particle separation. 2 dwg
