The idealized detector efficiency [equation (33)], taking into account the shadowing and the efficiency change due to the neutron path length within the cylindrical tube. (a) λ = 12 Å, ω = 0, (b) λ = 4.9 Å, ω = 0, (c) λ = 4.9 Å, ω = 20°, all with lateral movement of the detector xpiv = 0.5 m. The beam centre is marked with a cross. Intensities are normalized to 1. |
