Profiles of the vertical and horizontal focus measurements of doubly focused spots with a 18 keV monochromatic X-ray beam at beamline 1-BM using tungsten wire absorption scans. (a) Vertical focused beam profile; (b) horizontal focused beam profile. The size of the focus was 1.3 µm (V) and 1.2 µm (H). The inserts in (a) and (b) are the intensity of the tungsten wire scan in the vertical and horizontal directions, respectively. |
