(a), (b) Rectangular sample. (a) In the SESANS configuration, the sample is oriented perpendicular to the incident neutron beam. A scattering event changes the direction of the neutron trajectory by an angle α. (b) In the LD configuration, a neutron is Bragg-diffracted at a crystallite located at a distance x from the sample face. In the symmetric reflection configuration, the angles of the incident and outgoing neutron trajectories with the sample face are equal to the Bragg angle (θ1 = θ2 = θB). A small misalignment δ of the sample face leads to θ1 = θB − δ, θ2 = θB + δ. (c), (d) Cylindrical sample in (c) the SESANS and (d) the LD configuration.
