Schematic setup of an X-ray nanoprobe for SAXS/WAXS experiments. The incoming beam is focused by X-ray lenses onto the sample. A miniature ionization chamber detects the incoming beam flux. The diverging, transmitted X-ray beam is blocked by a small (∼250 µm) BS and only the sample SAXS and WAXS signal is recorded by the detector. The BS is filled with copper powder and the emitted Cu K fluorescence is detected by an APD. A sketch of the BS is shown in the inset. |
