Ray-trace simulation of the focused beam at the sample position. The focused photon beam dimension on the vertical plane (FWHM) = 48.0 ± 4 µm and on the horizontal plane (FWHM) = 158.7 ± 17 µm. The coloured histogram shows the energy resolution (entrance and exit slit 0.7 mm) giving 0.44 eV FWHM (0.18 Å). |
