frames, four motorized slits + 3 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)
