(a) Maximum count rate per pixel of the Eiger2 X 4M depending on the incident-beam photon energy. (b) Improvement of the (air-)scattering background with the reduction of pressure inside the flight tube, housing the Eiger2 X 4M detector. The presented data are frames averaged over 180 s. The images show the transmitted beam on the detector at 3.51 m distance from the focus, with a photon energy of 12.4 keV and a secondary source aperture of 8 µm (horizontal) × 5 µm (vertical).
