Instrumentation RX, diffusion aux petits angles (SAXS), diffraction de poudre
Responsable du service RX. Dans le cadre de ce service je suis en charge de l'utilisation et l'entretien des dispositifs SWAXS et DRX. Je réalise également la formation des utilisateurs et je participe aux traitement des données. Dans le cadre du développement instrumental je suis responsable de la mise en place du dispositif de diffraction en incidence rasante et du dispositif de diffusion aux petits angles, tous les deux montés sur une anode tournante Rigaku RU 200 (60kV, 200mA) 1. Dispositif SWAXS (Small and Wide Angle X-ray Scattering) Le dispositif SWAXS commercialisé par HECUS M. BRAUN est arrivé au laboratoire fin janvier 2008. Le montage est très compact (60cm contre plus de 250 cm, pour un montage SAXS classique) et il permet d'analyser des objets avec des tailles comprises entre 1.5 nm et 120 nm, (λ = 0.154 nm). La température de l'échantillon est régularisée entre 5 et 70°C à l'aide d'un dispositif à effet Peltier. 2. Diffractomètre de poudre INEL Le diffractomètre de poudre marque INEL est équipé d'un détecteur linéaire courbé qui couvre un domaine angulaire de 120°. Un monochromateur en Si assure la focalisation du faisceau sur le détecteur. La radiation utilisée est celle du Cu ( = 0.154 nm). Les échantillons sont disposés dans des capillaires positionnés verticalement.
