Abstract
L'invention concerne un appareil destiné à appliquer un rayonnement sur une région pour y réaliser des photo-excitations isotopiquement sélectives. L'appareil comporte deux miroirs réfléchissants 16 et 18 entre lesquels se trouve une région 12 dans laquelle est envoyé un courant de vapeur 14. Un rayon 20 vient frapper le miroir 18, puis effectue de multiples réflexions entre les miroirs 16 et 18 pour ressortir par-dessus le miroir 18. L'invention permet d'utiliser plus complètement l'énergie du faisceau de rayonnement sans pour autant présenter une très grande extension spatiale, ni exiger une intensité de faisceau trop élevée.An apparatus for applying radiation to a region for isotopically selective photo-excitations is disclosed. The apparatus comprises two reflecting mirrors 16 and 18 between which there is a region 12 in which is sent a stream of vapor 14. A ray 20 strikes the mirror 18, then performs multiple reflections between the mirrors 16 and 18 to emerge through above the mirror 18. The invention makes it possible to use the energy of the radiation beam more completely without having a very large spatial extension, nor requiring too high a beam intensity.
