Abstract

FIELD: production of radioactive isotopes of chemical elements. SUBSTANCE: method is designed as first enrichment stage of two-stage process of production of radioactive isotopes. Method includes ionization of vapors of separated substance, acceleration of ions by electrostatic field in ion source, separation of accelerated ions according to their masses in homogeneous magnetic field and accumulation of isotopes on receptacles. In this case isotopes of peripheral zone of cylindrical source of plasma are accelerated in radial direction by electrostatic field in closed cylindrical Hall layer of electrons with thickness of order of Lapmore electron radius. Circular paths of accelerated ions in transverse magnetic field and in electric equipotential space are set by change of relation of values of accelerating voltage and intensity of magnetic field so that mechanical limitation of travel of heavy ions occurs on radial coordinate and of light ions - on longitudinal coordinate. Device proposed for realization of method presents magnetic system arranged around vacuum chamber inside which source of accelerated ions with isotope receptacles is located. Source of ions is manufactured in the form of cathode and anode located on same axis in vacuum chamber. Two electrodes are receptacles of light ions and receptacle of heavy ions is fabricated in the form of cooled peripheral cylindrical electrode set coaxially to cathode and anode. For separation of isotopes of Ca where target isotope is Ca, operation of two stages for 460 H and accelerating voltage not exceeding several hundred volts are required to produce 1.0 g with 99 per cent by of Ca. EFFECT: increased operational efficiency of method. 2 cl, 2 dwg
