Title
(EN) OPTICAL DEVICE FOR ANALYZING A SPECIMEN BY THE SCATTERING OF AN X-RAY BEAM AND ASSOCIATED COLLIMATION DEVICE AND COLLIMATOR.
(FR) DISPOSITIF OPTIQUE POUR ANALYSER UN ECHANTILLON PAR DIFFUSION D'UN FAISCEAU DE RAYONS X, DISPOSITIF DE COLLIMATION ET COLLIMATEUR ASSOCIES.
Abstract
(EN) The invention relates to a collimation device for an X‑ray beam, to an optical device for analysing a specimen (105) by the scattering of an X‑ray beam, and a collimator for an X‑ray beam. The collimation device comprises an enclosure (110) intended to be under a vacuum or a controlled atmosphere, the enclosure (110) having an inlet (120) and an outlet (121) for the beam and at least one plate (104) made of a material having a diffracting periodic structure, said plate (104) having two main faces (104a, 104b) and at least one flared aperture (104c) between said faces.
(FR) L'invention concerne un dispositif de collimation pour un faisceau de rayons X, un dispositif optique pour analyser un échantillon (105) par diffusion d'un faisceau de rayons X et un collimateur pour un faisceau de rayons X. Le dispositif de collimation comprend une enceinte (110) destinée à être mise sous vide ou sous atmosphère contrôlée, l'enceinte (110) comportant une entrée (120) et une sortie (121 ) pour le faisceau ainsi qu'au moins une plaque (104) réalisée en un matériau à structure périodique diffractante, ladite plaque (104) comprenant deux faces principales (104a, 104b) et au moins une ouverture (104c) s'évasant entre lesdites faces.
