Figure 2
SHADOW simulations for LEG showing the images at the detector plane at selected photon energies: (a) 250 eV, (b) 300 eV, (c) 400 eV, (d) 500 eV, (e) 600 eV, and (f) 700 eV. In each figure, three photon energies are used for simulation with energy detuning listed on the top. (g) The amount of changes in included angle α + β (open blue squares, left axis) and the grating-detector distance rGD (red filled circles, right axis) with minimization of vector sum of aberrations F30 and F40. (h) Simulation showing the effect without minimizing the vector sum of aberrations at 700 eV. |
