DEVICE FOR SEPARATION OF CHARGED PARTICLES BY MASSES Russian patent published in 2001 - IPC

FIELD: nuclear technology; separation of isotopes from their natural mixture. SUBSTANCE: device includes vacuum chamber 1 where charged particle source 2, insulators 5, separator 6 and charged particles receivers 9 and 10 are arranged. Charged particle source 2 consists of ionizing chamber 3 and electrodes 4 forming extraction electric field. Separator 6 is made in form of widening bell-mouth 7 and narrowing bell-mouth 8. Both bell-mouths are mounted one in other near charged particle source 2 forming gap between their lateral surfaces. Bell-mouths 7 and 8 are provided with slots 11 located in plane of symmetry of separator 6. Gap on side of minimum radii of bending of bell-mouths 7 and 8 is greater than that on side of maximum radii of bending. Slots 11 are located on side of minimum radii of bending of bell-mouths 7 and 8. EFFECT: increased productivity and enhanced selectivity of separation. 2 dwg
