Abstract

Dispositif d’irradiation neutronique, comportant : une source de neutrons;un collimateur (30), disposé face à la source neutrons, délimitant un angle solide d’émission s’étendant autour d’un axe d’émission ; le dispositif étant caractérisé en ce que le collimateur comporte des écrans (31, 33) mobiles et agencés pour se rapprocher ou s’éloigner de l’axe d’émission ; de façon que la position de chaque écran, par rapport à la source de neutrons, permet une modulation spatiale et/ou spectrale du rayonnement neutronique.
