Time-of-flight (TOF), non-polarised This is achieved by a double chopper system using wavelengths from 2 to 27 Å with great flexibility in resolution. This mode can simultaneously cover an order of magnitude

Off-specular scattering in 2θas recorded on D17 from lipid bilayers. Lipid bilayers and thermal fluctuations Lipid bilayers are increasingly used as ideal models of cell membranes. They are characterised ... one dimension giving rise to Bragg diffraction peaks. The figure shows the off-specular scattering in 2θ stemming from thermal fluctuations. ...

ThALES is optimized for the measurement of excitations in single crystals in the range of about 0.2 to 10 meV. With its high neutron flux, which is worldwide leading, and its very low background, it can ... meV, depending on the incoming neutron energy Unrivalled cold neutron flux at the sample position (2.5·108 n/cm2/s for incident energies ...

in respect to each other. If one of the crystals is transversally displaced by one lattice constant (2Å) a phase shift of 360° is introduced. Consequently, a sub-picometer stability is required over the

Its reflectivity is particularly high at wavelengths about 1.7 Å using the (400) reflection and at 2.5 Å using the (311) reflection.

diffractometer of choice for determination of crystal structures with unit cells in the range of 10 2 to 10 6 Å 3 . It is also unique for fibre diffraction studies of biological and industrial fibres.
