Title
(EN) BACK-REFLECTION LAUE DETECTOR AND METHOD OF OPERATING THE SAME
(FR) DÉTECTEUR DE LAUE RÉTRO-RÉFLÉCHISSANT ET PROCÉDÉ DE FONCTIONNEMENT ASSOCIÉ
Abstract
(EN)
A back-reflection Laue apparatus and a method are provided. The apparatus includes a source for generating X-ray radiation, a collimator for collimating the X-ray radiation into an X-ray beam; a back-reflection Laue chamber for transmitting the beam therethrough towards a sample, and back-reflecting visible radiation obtained from the beam being diffracted off the sample and converted to visible radiation upon re-entering the chamber, the chamber comprising a reflection side wall having an exterior surface and a reflective interior surface for back-reflecting the visible radiation, the wall being provided with a through-hole extending from the exterior surface to the reflective interior surface; and a detector assembly for detecting the back-reflected visible radiation. The collimator has a first end connected to the source and a second end terminating between the exterior surface and the reflective interior surface of the wall, within the through-hole, the beam exiting the collimator at the second end.

L'invention concerne un appareil de Laue rétro-réfléchissant et un procédé associé. L'appareil comprend une source de génération d'un rayonnement de rayons X, un collimateur pour collimater le rayonnement de rayons X en un faisceau de rayons X ; une chambre de Laue rétro-réfléchissante pour transmettre le faisceau à travers celle-ci vers un échantillon, et un rayonnement visible rétro-réfléchissant obtenu à partir du faisceau qui est diffracté à partir de l'échantillon et converti en un rayonnement visible lors de la ré-entrée de la chambre, la chambre comprenant une paroi latérale réfléchissante ayant une surface extérieure et une surface intérieure réfléchissante pour rétro-réfléchir le rayonnement visible, la paroi étant pourvue d'un trou traversant s'étendant à partir de la surface extérieure jusqu'à la surface intérieure réfléchissante ; et un ensemble détecteur pour détecter le rayonnement visible rétro-réfléchi. Le collimateur a une première extrémité reliée à la source et une seconde extrémité se terminant entre la surface extérieure et la surface intérieure réfléchissante de la paroi, à l'intérieur du trou traversant, le faisceau sortant du collimateur au niveau de la seconde extrémité.
