Abstract

L'INVENTION CONCERNE UN PROCEDE ET UN APPAREIL D'IONISATION DE PARTICULES D'UN TYPE ISOTOPIQUE CHOISI DANS UN ENVIRONNEMENT DE PLUSIEURS TYPES ISOTOPIQUES. L'APPAREIL COMPREND UN MOYEN D'EXCITATION SELECTIVE DES PARTICULES DU TYPE ISOTOPIQUE CHOISI A UN ETAT EXCITE, ET UN MOYEN D'APPLICATION DE RAYONNEMENT ELECTROMAGNETIQUE D'UNE LARGEUR ET D'UNE FREQUENCE SPECTRALES PREDETERMINEES QUI EST ACCORDE SUR UNE RAIE D'ABSORPTION DES PARTICULES DANS LEDIT ETAT EXCITE, LEQUEL RAYONNEMENT EXCITE LES PARTICULES A UN ETAT D'AUTO-IONISATION AU MOYEN D'UNE FREQUENCE PREDETERMINEE ABSORBEE PLUS FORTEMENT QUE LES FREQUENCES IMMEDIATEMENT ADJACENTES. CES MOYENS PEUVENT ETRE DES FAISCEAUX LASERS 46 AGISSANT A L'INTERIEUR D'UNE CHAMBRE 40 REMPLIE D'UNE VAPEUR D'URANIUM 54. UN MOYEN SEPARATEUR 52 EST EGALEMENT PREVU. L'INVENTION S'APPLIQUE A LA SEPARATION DE L'URANIUM-235, NOTAMMENT.THE INVENTION CONCERNS A PROCESS AND AN APPARATUS FOR IONIZING PARTICLES OF AN ISOTOPIC TYPE CHOSEN IN AN ENVIRONMENT OF SEVERAL ISOTOPIC TYPES. THE APPARATUS INCLUDES A MEANS OF SELECTIVE EXCITATION OF PARTICLES OF THE ISOTOPIC TYPE CHOSEN IN AN EXCITED STATE, AND A MEANS OF APPLICATION OF ELECTROMAGNETIC RADIATION OF A PREDETERMINED SPECTRAL WIDTH AND FREQUENCY THAT IS GRANTED ON AN ABSORPTION RATING PARTICLES IN SUCH EXCITED STATE, WHICH RADIATION EXCITES THE PARTICLES TO A STATE OF SELF-IONIZATION BY MEANS OF A PREDETERMINED FREQUENCY ABSORBED MORE STRONGLY THAN THE IMMEDIATELY ADJACENT FREQUENCIES. THESE MEANS MAY BE LASER BEAMS 46 ACTING INSIDE A CHAMBER 40 FILLED WITH A URANIUM VAPOR 54. A SEPARATOR MEANS 52 IS ALSO PROVIDED. THE INVENTION APPLIES TO THE SEPARATION OF URANIUM-235, IN PARTICULAR.
