group, were carried out at D11. The scattering curves show a q -4 dependency at high q (indicating densely packed objects with sharp boundaries) and a maximum with adjacent minimum at lower q. Experimental ... scattering curves are compared with theoretical models. Neither a sphere nor a cylinder form factor can render the measured curve and are ...

In this regime there is a simple functional relationship of the type h z e-as between the shear viscosity and the order parameter S, with a common slope a for all samples over a wide range of concentrations ... copolymer micelles was investigated at D11 over a broad range of shear rates and concentrations with rheo-SANS, a powerful technique that ...

particle–hole excitation of a spinon Fermi surface. The results therefore point to the existence of a quantum spin liquid state with a spinon Fermi surface in YbMgGaO 4 , which has a perfect spin-1/2 triangular ... spin excitations, covering a wide region of the Brillouin zone. The observed diffusive spin excitation persists at the lowest measured ...

along the c-axis. Here the low-energy excitation spectrum of Nd0.05 Ce0.95 CoIn5 was measured, where a spin resonance was observed. The spin resonance is only observed for temperatures below Tc, and has

the ILL and delivered at the end of 2022. Major components such as a new granite platform, a new detector table mounted on air-pads and a new flight chamber, were part of the upgrade, all designed to make ... the new detector. The upgrade represents a 5-fold gain and a significant improvement of the data quality. Applications The strength of the ...

A rocking curve from a membrane multilayer recorded with the 256 x 256 mm2 detector. D16Watch the successive peaks which appear while the sample is rotated. Here the sample is a crystallized dilute lamellar ... detector Until 2009, the neutron detector of D16 was a 3 He bidimensionnal detector with an area of 256 x 256 mm 2 , a resolution (pixel ...

MILAND, the new detector MILAND, a highly performing detector, will be installed on D16 by the end of 2009 or the beginning of 2010. We show here a test pattern from a deuterated lysozyme crystal.

monochromator (mosaicity <0.5°). Double bouncing Bragg or supermirror filter cutting higher harmonics by a factor of 104. Highly sophisticated polarisation option. Low resolution option : monochromator made ... of intercalated graphite (higher mosaicity, focusing, considerably higher neutron flux) resulting in a large dynamical range.
