Figure 7
(a) The simulated and measured total flux (Φn) and (b) the total intensity over the area of a four-grating mask ([I_{n}^{\,{\rm{G}}}]) consisting of 50 µm × 50 µm gratings arranged symmetrically with a 50 µm gap in the centre (shown in inset, where the gratings are shown as black squares, the n = 1 harmonic in blue, and the n = 3 harmonic in green). Flux and intensity measurements were taken at branch B, while flux measurements were also taken on branch A using an AXUV100 photodiode. Cff = 1.4 for all measurements shown.
