The ESRF magnetic scattering beamline has been optimized for easy tunability of the polarization and energy in the 3–40 keV range. The linear horizontal polarization from the undulator reaches 99.9%, with a flux of ∼10 12 photons s −1 at the sample. The diffractometer can operate in horizontal and vertical geometries, with an energy or polarization analyser. The capabilities of this beamline in terms of flux, energy tunability and polarization, permitted polarization analysis of resonant magnetic scattering from antiferromagnetic UPd 2 Si 2 at both the L 2 ‐ and M 4 ‐edges of uranium, to separate the contributions of the 5 f and 6 d electrons to the magnetism.
