Experimental setup of the microbeam experiment at BL20XU at SPring-8 (top view). The undulator light source and double-crystal monochromator are omitted. FZP: circular FZP, circular A-FZP, 1D FZP and 1D A-FZP with the same focal length of 100 mm were installed one after another. OSA: order-sorting aperture (platinum pinhole with diameter of 20 µm for circular FZPs, tantalum slit with 20 µm width for 1D FZPs). A cross slit with an opening width of 50 µm × 50 µm is used for defining the effective X-ray source size. |
