Figure 6
Images of the X-ray beam at the sample position collected with an area-sensitive ionization detector at a wavelength of 1.3 Å. The first photograph (a) was taken with an unfocused monochromator and a focused mirror showing a spot size of 7 mm × 0.5 mm (FWHM). In the second photograph (b), both the mirror and monochromator are focused. The spot size is here 1 mm × 0.5 mm (FWHM). |
