(a) Top view of a one-dimensional array of X-ray prisms, nanofabricated from Si, with varying prism angle in each channel. (b) The second family of prisms used in this study. (c) Schematic (not to scale) of the experiment, illustrating the creation of a pair of virtual sources from a single real source. (d) SEM image of the Cr-capped Si wall that serves as the `knife edge' for X-ray fluorescence. |
