The idealized efficiency [equation (33)[link]] of single voxels. (Top row) ϑ = 0. (a) A single voxel as seen from the sample position. The colour is related to the neutron flight path distance in the voxel. (b) The idealized efficiency of a non-shadowed voxel. (c) The idealized efficiency of a shadowed voxel with [|\varphi| \,\gt\, \varphi_{\rm crit}]. (Bottom row) ϑ = 25°. (d) A single voxel as seen from the sample position. (e) The idealized efficiency of a non-shadowed voxel. (f) For [\vartheta \,\gt\, 0], the neutron path length is truncated at the lower plane of the neighbouring voxel within the same tube. Additionally, the voxel is shadowed by the neighbouring tube for [|\varphi| \,\gt\, \varphi_{\rm crit}].
