very low background, it can be used to measure particularly weak signals. It allows for extreme sample environment (low temperature, high magnetic fields and pressure) and can be used with neutron polarization ... phenomena, magneto-elastic or multiferroic materials, and heavy-fermion systems, among others. It can also be used for high-precision ...

resolution the monochromator curvature can be reduced both in the horizontal and in the vertical plane (down to flat positions) and the elliptically tapered guide end-section can be replaced by a straight m = 1

parameters can be drawn against the left or right y-axes in the same plot. Pattern plotter for the visualization of powder data. Powder patterns can be offset, added or subtracted. A series of patterns can be ... different style spin envelopes can now be drawn with an envelope edge, split sites can optionally show the occupations by drawing atoms ...

cryomagnet: para-, ferro- and some antiferro-magnetic form factors, magnetisation distributions,etc. Data can readily be analysed on the ILL computing system by a system of programs making use of the Cambridge

the advanced 3He dilution cryostat This cryostat, the only one of its kind in the world as of 2009, can reach 65 mK. Its operation mode is independent of gravityation, which makes it possible to follow the

intensities of a large number of Bragg reflections, from which the atomic structure of the sample can be obtained.

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 mode). This dilution

length L then changes abruptly over a short period ξ (Fig. 3). Close to T* the magnetic structure can be pictured as a periodic structure of domains which are separated by domain walls or equivalently

intermediate states like cigars or pearl necklaces along this shrinking process. Structural changes of PE can be induced by e.g. alkali and alkaline earth halides. Furthermore, the interaction between PE and metal ... scattering curves are compared with theoretical models. Neither a sphere nor a cylinder form factor can render the measured curve ...

D11 over a broad range of shear rates and concentrations with rheo-SANS, a powerful technique that can be used to obtain a detailed molecular picture of the structural changes of complex fluids under shear ... objects such as wormlike micelles align in the flow direction, with an orientational distribution that can be well described by an ...
