(a) Bent and ground Johansson monochromator. The outer arc represents the bent lattice planes of the monochromator crystal (the curvature centre is A and the radius is 2R, where R is the radius of the Rowland circle, shown by the black circumference). The Rowland circle lies on the surface of the ground crystal. The red dots represent 2n + 1 surface points distributed on a `crystal fan' with a constant angular offset. (b) The 2n + 1 discrete crystals have been rotated (see text). In both (a) and (b) the central crystal O, the source S and the focus point D are shown.
