The beamline is operated in the energy-dispersive mode of diffraction using the direct white photon beam provided by a superconducting 7T multipole wiggler. The wigglers critical energy is 13.5 keV at 1.7 GeV. The figure below shows its energy spectrum recorded directly without any attenuators in the beam by means of a Germanium solid state detector (Canberra).
