Far-field diffraction patterns at the detector for the table-top source (λ = 0.154 nm); (a,c) experimental results; (b,d) computer simulations. From the computer simulations it results that the WG in (a) and (b) has a length of 4.5 mm, a tapering angle α = 4 × 10−5 rad, a gap at the entrance din = 150 nm and a gap at the exit dex = 330 nm. The WG shown in (c) and (d) has a length L = 4.9 mm, a tapering angle α = −2.2 × 10−5 rad, din = 305 nm and dex = 200 nm.
