The benefits of having 6 legs One of the principal challenges during strain experiments is the movement of the specimen about the neutron beam (gauge volume). SALSA uses a unique hexapod design which

An advanced neutron strain analyser SALSA is designed for actually performing diffraction measurements on "real" engineering components and is optimised for stress determination in metallic components

The stress scanner Measuring residual stress in a material amounts to making a map of its local deformations. Just like a medical scanner makes an image of the human body interior, what is sought here

Deformations and diffraction Measuring residual stress via diffraction relies on a tight correlation between macroscopic deformations (the concern of engineers) and the variation of diffraction angles

Determining layer thickness Neutrons are no longer reflected from a single surface but from two semi-transparent surfaces. The reflectivity curve still has a total reflection plateau but the descendin

Neutron reflectometry examines the way in which surfaces or interfaces reflect neutrons in order to provide information on their organization, thickness, composition and roughness. Layer stacking can

Shear viscosity h as a function of shear rate for cylindrical micellesThese are PB-PEO-16: c =10 g/l (n,r), CPySal: c =20 g/l (l,m) and CTAB: c =20 g/l (r).Filled symbols are upward, open symbols are

The trick of the advanced dilution cryostat of D10 A neutron radiograph film recorded at the ILL in 2005 on NEUTROGRAPH shows the progressive dilution of helium-3 into helium-4 inside a capillary whic

4-circle diffraction with a 3He dilution cryostat In the four-circle mode, the offset C-shaped Eulerian cradle can be equipped with a helium-flow cryostat (1.6 K to 450 K, or 0.1 K to 10 K in dilution

Simulated experiment (TAS geometry) Here D10 is set in the 3-axis geometry (TAS geometry) for an inelastic scattering experiment. The polychromatic beam from the thermal neutron guide H24 arrives on t
