From: Ellipsoidal mirror for two-dimensional 100-nm focusing in hard X-ray region
Measured intensity distributions in focal plane. The intensity distributions reflected from two areas of the ellipsoidal mirror are evaluated using the knife-edge scanning method at X-ray energy of 7 keV. One has a total area of 93 mm × 0.45 mm. The other is the 50 mm × 0.45 mm central-part area. The corresponding profiles are shown in (a) and (b) and in (c) and (d), respectively. (a) and (c) Focusing-beam profiles in the meridional focusing direction. (b) and (d) Focusing-beam profiles in the sagittal focusing direction. The evaluated focus sizes are 95 nm × 132 nm and 85 nm × 125 nm (FWHM), respectively.
