Figure 2
Image from Karabo focusing scene used to validate and optimize focus during alignment at the start of each user shift. The focal spot is only a few pixels with 1.042 µm per pixel. The measured effective FWHM (provided in Karabo to enable optimization) of the IRD focal spot is routinely ∼2.50 µm (in this case with 12.8 keV X-ray energy) using the direct beam trajectory. A similar effective FWHM is also achievable in the IRD for the refocused micrometre KB trajectory.
