Figure 2
Schematic diagram of the experimental set-up. FZP: Fresnel zone plate; OSA: order-selecting aperture. f ≃ 53.3 mm at 8 keV for third-order diffraction. Effective source size: ∼100 µm (vertical, 47 m from FZP), 10 µm slit (horizontal, 9 m from FZP). FZP material: Ta, 1µm-thick. Outermost zone width: 0.25 µm. Center stop: gold, 2.4 µm-thick, diameter 50 µm.
