First experiment with the 3He neutron spin filter During this first test of an 3 He neutron spin filter, the neutron-beam polarisation transmitted by the filter could be determined with high accuray f

CCSL | FullProf | Liquids CCSL CCSL is a library of subroutines for doing crystallographic and related calculations. It is designed not so much as a set of programs for determining and refining struct

Simulated single crystal diffraction experiment Here D10 is set for a single crystal diffraction experiment in the 4-circle geometry. The polychromatic beam from the thermal neutron guide H24 arrives

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

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

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

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

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

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

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
