Fig. 1. (a) Schematic overview of the experiment setup. L–N means the laser is interacting with the nanowire structure directly. L–S means the laser is interacting with the substrate; (b) scanning electron microscopy image of the nanowire array target.
Fig. 2. (a) Spectrum of K-shell lines obtained for 94.8 J laser incidence on the target with 20 μm nanowires; (b) dependence of the total count of K α
Fig. 3. (a) Original K α 1 × 10 19 W / cm 2
Fig. 4. (a) Stack of 1D slits (50, 100, 200, and 300 μm) on a 50 μm thick Ta substrate; (b) horizontal line-outs for the point projection radiography.
