Ni (left) and Cu (right) Kα peaks reflected from a 200 HUF coin onto the detector via the conical von Hámos crystal. Panel (a) shows experimental data, panel (b) the result of the ray tracing. Abscissas share the same scale, shown in pixel numbers in (a) and distances in millimetres in (b). The CCD detector has 26 µm × 26 µm pixels. |
