Title: Method and apparatus for separating isotope
Inventor: SHIODA KAZUNORI
IPC: B01D59/34
Filed: 1989-12-25
Abstract: PURPOSE:To enhance the separation capacity of an isotope by decomposing the polymolecular composite in the vapor stream of a substance containing a specific isotope into monomolecules and supplying a genuine monomolecule vapor stream to an isotope separation process. CONSTITUTION:A glow discharge region 24 is formed to the vapor flow passage 18 of the vapor stream inlet part of a photoreaction region 10 where a vapor stream is ionized by ionizing laser beam 11 in timewise synchronous relation to the ionizing laser beam 11. The vapor stream 17 passed through the glow discharge region 24 is supplied to an isotope collector 9 during a time zone when the laser beam 11 and the vapor stream 17 are subjected to photoreaction. As a result, the cluster (polymolecular aggregate) contained in the vapor steam 17 is decomposed into monomolecules during the time when the laser beam 11 and the vapor steam 17 are subjected to photoreaction by the electron impact in the glow discharge region 24. By this method, a selectively ionized isotope is efficiently separated from a genuine molecule vapor stream almost composed of the monomolecules of the constituent particles in the vapor steam 17. As a result, the separation efficiency of an isotope can be enhanced.
