Figure 6
All reported results refer to an FG with f = 1 and p = 600 nm. (a) Intensity transmitted (n = 0, central spot) and diffracted (n = ±1, multiplied by 50) by the FG at a photon energy of 150 eV. (b) Numerical simulation of the results shown in (a), using the nominal FG parameters. (c) Accumulation of seven scattering patterns (n = ±1) at varying photon energies over the 130–330 eV range, while keeping the positions of the FG and CCD detector fixed. (d) Diffraction orders up to n = ±7 at a photon energy of 778 eV. The n = 0 beam is blocked by a beam-stop. Relative to n = 1, the intensity is multiplied by 20 for n = 2, 3 and by 100 for n ≥ 4. (e) Numerical simulation of the results shown in panel (d). (f) Points: experimental θ values for several diffraction orders at λ ≃ 6.9 nm (180 eV). Line: fit with |L|1/2 dependence. (g) Experimental θ values versus λ for three diffraction orders over the ∼1–10 nm range, corresponding to the 130–1180 eV photon energy range. |
