4-circle geometry. The polychromatic beam from the thermal neutron guide H24 arrives on the monochromator, which selects a given wavelength. The monochromatic beam passes through slits to limit its size ... planes diffract into the equatorial plane. The detector is rotated to the location of the diffracted beam, which is then scanned step by step. ...

frames, four motorized slits + 5 XY multi-holes diaphragms in 10 B 4 C to have full control over the beam shape including when gravity plays a role and guarantee the smallest achievable background for low

provided by a Δλ/λ = 0.01 combined to 1D slit collimation or 2D pinhole collimation provides a flexible beam geometry adapted to various sample shapes and sizes and scattering geometries. This flexibility allows

for Grazing Incidence Small-Angle Neutron Scattering. By restricting the divergence of the incoming beam in the direction perpendicular to the scattering plane three dimensional information becomes accessible

multilayer sample approximation gives realistic results: this suggests the possibility to use neutron beams to study very diluted systems such as MNCGs. (Courtesy of C. Mondelli)

ght (TOF), polarised beam This is achieved by using an S-bender polarising the TOF beam in a selectable wavelength range with high polarisation. The instrument resolution and beam shape remains flexible ... GISANS possible.

but the descending portion shows the presence of oscillations resulting from interference between beams reflected by the two surfaces. The size of these oscillations is related to the layer thickness. The

Taking advantage of the easy access around the D17 sample mount, together with the high flux and beam stability, an experimental configuration has been devised to simultaneously collect reflectivity and
