La méthode DNPA (SANS : small angle neutron scattering) [...] consiste à irradier avec un faisceau parallèle de neutrons l'échantillon à analyser. Les hétérogénéités chimiques du matériau provoquant une diffusion des neutrons incidents au petits angles, l'analyse de l'intensité diffusée permet de caractériser ces hétérogénéités. Cette méthode est largement utilisée pour quantifier (taille et densité) les petits amas de soluté ou les petites cavités dans les aciers irradiés. C'est une méthode complémentaire de la microscopie électronique en transmission ou de techniques comme la sonde atomique. Contrairement à ces deux techniques précédentes, la DNPA ne permet pas la visualisation directe des hétérogénéités; cependant, elle est moins locale donc plus statistique que ces dernières. 1, record 1, French, - diffusion%20des%20neutrons%20aux%20petits%20angles

Diffusion à «petits angles». Les neutrons sont caractérisés par une longueur d'onde [lambda] d'environ 1 nm (10-9m). Lorsqu'un faisceau de neutrons rencontre un échantillon possédant une structure à «grande échelle» (1 nm à 100 nm), faite d'au moins deux espèces, il est diffusé à un angle [thêta] petit, d'où le nom de diffusion à petits angles. L'intensité diffusée est proportionnelle à un contraste naturel entre les deux espèces ou obtenue par une substitution isotopique. 1, record 2, French, - diffusion%20%C3%A0%20petits%20angles

Particle sizes and distribution can be successfully measured using low angle laser light scattering (LALLS). This technique uses a light source of known wavelength to cause oscillation of the dipoles present in the particles. The electromagnetic energy released from these oscillating dipoles, known as secondary radiation, radiates out in all directions except along the axis of oscillation. The ratio between the wavelength of incident radiation and the particle size will determine the actual light scattering pattern from the particle. 3, record 4, English, - low%2Dangle%20laser%20light%20scattering

Diffraction de lumière laser aux petits angles. Lorsqu'une particule sphérique est éclairée par un faisceau parallèle de lumière cohérente et monochromatique, un motif de diffraction vient se superposer à l'image géométrique. Ce motif est grand par rapport à l'image, les petites particules diffractant la lumière suivant un angle plus grand que les grosses particules. Une gamme granulométrique peut être divisée en intervalles de taille qui génèrent chacun un motif de diffraction en fonction de sa taille moyenne, avec une intensité fonction du nombre de particules qu'il contient. On peut donc obtenir la distribution granulométrique en analysant le motif de diffraction. 1, record 4, French, - diffraction%20de%20lumi%C3%A8re%20laser%20aux%20petits%20angles
