Figure 2
Simulations for the photon flux depending on photon energy to be expected at the exit slit behind a prism array with the parameters and the boundary conditions reported by Liu et al. (2012  ). From the bottom to the top the calculations are for a symmetric prism array lens and for exit slits measuring 24 (red line), 16 (black), 40 (green) and 80 µm (blue) as an approximation for 25% larger circular apertures with diameters of 30, 20, 50 and 100 µm, respectively. The maxima are made to coincide at the operation energy of 15.7 keV, with the exception of the calculation for the 16 µm slit which is put 60% higher. The latter modification was also made by Liu et al. (2012) in their presentation of experimental data. |
