Figure 2
Schematic illustration of the test measurement geometry; monochromatic X-rays of energy 14 keV are incident on a Fresnel zone plate (FZP), whose first-order focus, selected by an order-sorting aperture (OSA), illuminates a sample aligned at 45° to the beam. A TTL pulse (master trigger) triggers the simultaneous recording of: the incident beam intensity with a thin silicon photodiode (I0), the transmitted beam intensity with a pixel array detector (D) (P: recorded transmission pattern), the emitted fluorescence with an energy-dispersive detector (F), and the encoder positions of the sample scanning stage.
