Acceptance properties for X-ray waveguides depending on effective thickness for the tested material combinations Mo/Be and Cr/C (solid lines) for a photon energy of 13 keV. (a) FWHM spatial acceptances AFWHM according to (13) and (b) related angular acceptance ΔφFWHM from (14). The dashed lines in (a) refer to the FWHM spatial acceptances for waveguides with exchanged cores in Mo/C and Cr/Be combinations. |
