Supported by TECHNI (Technology for Neutron Instrumentation) Project Plan in its initial version (April 2000) The aim of the project is to develop and to build a real-time neutron detector for small-angle scattering ... small-angle neutron and X-ray scattering J. Mol. Biol. 345, 797-815 7. Heller, W.T., Finley, N, Wen-Ji D., Timmins, P., Cheung, ...

main instruments used for College 5C proposals are: D17 , Neutron Reflectometer with Horizontal Scattering Geometry D11 , Small-Angle Neutron Scattering Instrument D22 , Large Dynamic Range Small-Angle

to control the structural disorder through doping. The defect structures have been studied with neutron Laue diffraction using SXD at ISIS and will be compared with first-principles density-functional ... In addition, the spin correlations have been measured using the diffuse scattering of polarized neutrons using D7 at the ILL.

helical slot (ASTRIUM) velocity selector which selects neutrons of ±9 % about a mean wavelength determined by the rotation speed of the drum. The neutrons are then collimated by a series of moveable glass guides ... 99.5 % at λ = 0.45, 0.6 and 1 nm within the tubes. Due to the geometry of tubes assembly, 12 % of neutrons avoid the detection area. ...

experiment very high energy resolution is achieved by encoding the neutron energy into a Larmor precession angle: Polarized neutrons are sent through two anti-parallel magnetic fields before and after ... opposite, so that for elastic scattering full polarization is recovered, irrespective of the initial neutron velocity distribution.
