Les appareils d'Orphée; Orphée neutrons spectrometers

Le réacteur Orphée a fourni des faisceau de neutrons dédiés à l'étude de la matière condensée de 1980 à 2019. Plus d'une vingtaine d'appareils de diffusion et diffraction de neutron de tout type étaient disponibles sur Orphée. On trouvera leur description sur cette page.

Les différents types d'appareil :

 

The Orphée reactor did provide neutron beams for the study of condensed matter from 1980 to 2019. More than 20 instruments of neutron scattering were available there. A short description of them may be found there.

A short description of the different types of spectrometers that were available can be found there :

Simeon Minic, Burkhard Annighofer, Arnaud Helary, Djemel Hamdane, Gaston Hui Bon Hoa, Camille Loupiac, Annie Brulet, and Sophie Combet To probe intermediate states during unfolding and oligomerization of proteins remains a major challenge. High pressure (HP) is a powerful tool for studying these problems, revealing subtle structural changes in proteins not accessible by other means of denaturation.

Chang Liu, Wenxian Hu, Hanqiu Jiang, Guoming Liu*, Charles C. Han, Henning Sirringhaus, François Boué, and Dujin Wang The determination of intrinsic chain stiffness of conjugated polymers is challenging, in particular, for scattering techniques because of their strong light absorption and structural instability due to the complicated intra-/intermolecular interactions.

Li Shi, Florent Carn, Arsen Goukassov, Eric Buhler, and François Boué Mixing negatively charged polyelectrolyte (PEL) with positively charged gold nanoparticles (Au NPs) in aqueous solution results in electrostatics complexes of different shapes and compactness. Here, when complexing with a semirigid PEL hyaluronic acid (HA), we obtain crystals made of nanoparticles in a new region of the phase diagram, as evidenced by small-angle Xray scattering (SAXS).
